MySql slowdown over time

I have a apache2/php5/mysql5 setup on tiger. The wordpress site runs fine to start with, but after a while (usually a couple of hours) the site slows down upon every request. When the slowdown occurs there is also a lot of disk activity, like something is being cached on disk. The Mac Pro has 8GB Ram installed so its not a shortage of resources. When I restart the mysql service the problem goes away for a few hours then repeats. I have scripted a service restart cron job every hour to get around this but if anyone has come across this before can the sing out!!

Never found the answer but an upgrade to leopard sorted the issue.

Setup a new Macbook Pro to minimize application slowdowns over time

Hi,
I own a dual G5 2.0 tower which has become (over time) extremely slow...it seems I get the spinning beachball all too often, but have plenty of ram and HD space. Even when opening JPEGS.
I am buying a macbook pro this w/e and was wondering what the best way to setup the new computer because I want to use it as an HD FCP editing station (on location), but from time to time use applications like aquisition and bittorrent which really seem to bog the system down. I assume not using migration assistant, and re-installing from scratch is a good idea.
Forgive what may be basic questions, but do I setup a partition initially on the internal drive (and have 2 system folders or something similar?) or will simply setting up different users to access only certain applications help? (I assume not).
Obviously a concern is the laptop drive is small 160GB 7200RPM but I can guess most of the time I will be running a GRAID for the video editing files, and bigger aperture library (I may have a small select library on the internal drive to show clients and friends "on the go")
I really appreciate any tips or suggestions and hope that my questions make sense. I realize I want the computer to "do it all" but can't afford it to be strictly an editing station, as I'll be selling the G5 to help pay for the macbook pro!
Much appreciated,

Understand that P2P software operates under the premise that you will have many connections to peers. Each network connection requires memory and CPU cycles to operate properly without timing out the connection or slowing down transfers. In fact, the faster the Internet connection and the more peers connected to your P2P application, the more resource intensive the P2P software will be. You will want to either close the P2P application or tweak it's settings so that it uses minimal bandwidth and resources while you are performing other tasks on your MBP. Try Azureus for torrents as it allows you to tweak settings very nicely.
Partitioning your hard drive will accomplish nothing in this case. Better to invest in an external FW800 drive for the improving performance while video editing or where you need additional storage.

Slowdown over time

I have a quad core MacPro1,1 w/7GB RAM - it used to be really fast. Now it suffers incredible slowdowns when opening applications and files. Firefox takes 60+ seconds to load and crashes often. Other apps pause at the file open dialog. I usually hear a lot of disk activitiy during the slowness. I hoped upgrading to snow leopard would restore previous performance but no luck.
Any tips on increasing speed or clues to understand why the slowdown?

How much space is available on your hard drive? Having a full (or nearly full) hard drive can really slow your machine down. Many users recommend having as little content as possible on your main system drive other than your apps and system files (i.e. move things like iTunes libraries, photos, etc. to another hard drive). This allows more of your files to reside on the fast outer tracks of the disk. Since you have a tower and can easily add another internal drive, I'd recommend doing this. Internal hard drives are pretty cheap these days, you can find 1TB drives for less than $100.
You might also look into defragmenting your drive. There's some debate over whether or not one should defrag on a Mac, since the OS does the bulk of it for you. However, in my personal experience, it does help smooth performance.
There are a lot of other things that could be causing this slowdown, but the HD is a good first place to look.

Slowdown over time using tomcat

I have a search which finds a route through the london Underground... it uses JSP's and a servelet.
The application is run over tomcat.
My problem is that in testing it seems that restarting the Tomcat server makes my searches quicker... a lot quicker in some cases.......
I wonder if anyone who has used tomcat in a similar way has come across this problem and resolved it without having to restart the Tomcat server after each search.
Cheers

Looks like you have a Shlemiel the painter's algorithm going on somewhere in your code. Who is Shlemiel? He's the guy in this joke:
Shlemiel gets a job as a street painter, painting the dotted lines down the middle of the road. On the first day he takes a can of paint out to the road and finishes 300 yards of the road. "That's pretty good!" says his boss, "you're a fast worker!" and pays him a kopeck.
The next day Shlemiel only gets 150 yards done. "Well, that's not nearly as good as yesterday, but you're still a fast worker. 150 yards is respectable," and pays him a kopeck.
The next day Shlemiel paints 30 yards of the road. "Only 30!" shouts his boss. "That's unacceptable! On the first day you did ten times that much work! What's going on?"
"I can't help it," says Shlemiel. "Every day I get farther and farther away from the paint can!"

Significant slowdown of Time Machine after upgrade to Lion; indexing problem

After upgrading to Lion over the weekend I notice a significant slowdown of Time Machine processing. I assumed the first backup or two would take some time but it's been a couple of days. The process always hangs up at the "Indexing backup" stage. It takes a couple of hours to finish.
I found several threads relating to slowed down backups on Lion, most seem to hang at the "Preparing" stage (not the same symptom) but I did find some good diagnostic pointers. I installed the widget to see what kind of messages were being produced and found a few dozen "Waiting for index to be ready (100)" messages at the end of the stream. Further research - this is not a good thing :-) It seems a couple of such messages can be ok, but this many usually indicates a problem. I'm going to discount the possibility of a hardware failure because everything was perfectly fine up to the point I made the upgrade. Plus the prepare and copy seem to proceed at the expected speed (I watched the most recent cycle just to be sure).
Here is the full message log (it's still running at the moment):

I further found the advice and instructions on how to run the disk utility on the sparsebundle. I did a verify and repair, and the results came back that the drive appears to be ok (it did not say that it explicitly repaired anything).
But the problem remains.
I use a 1TB Time Capsule with plenty of free capacity (only half full). The TC and my MacBook are both hardwired into the home network, networking speed has never been an issue.
I'd sure hate to delete the backup file and start from scratch, there's over a year's worth of data there and I have, occassionally, wanted to go in there and pick up a downlevel or subsequently deleted file.
Any advice on other diagnostics or repair options to take? Thanks!
Paul

After posting I decided to keep trying to slog my way through the troubleshooting guide. Some of the steps are beyond my understanding but I did follow the advice in #D2 to delete the .Spotlight-V100 file from the sparsebundle. That action does seem to have done the trick, the backups are now completing in normal time. I ran a couple just to be sure. I've verified the backups with BackupLoupe and entered the Time Machine, all appears to be in order and as expected. The only odd side effect is that the backup volume is no longer ejected after completion but that might just be an artifact of all my mounting/de-mounting and playing with Finder. Anyway a very small price to pay for what looks to be a working system again.
Hopefully the good behavior will last through a few days and a few reboots :-)

Audio performance deteriorating over time until Mavericks reinstall

I'm on the latest Mavericks, maxed-out 12-core Mac Pro. I use Steinberg Nuendo as my main audio DAW. It works like a dream... for a while... But after a few weeks it starts slowing down until Nuendo is almost unusable. Larger projects which normally run just fine become unworkable or very sluggish because they just overload the CPU, as if I was working with a 5 year old computer. This issue specifically targets audio performance, whether I use internal audio or my audio interface (UAD Apollo).
I've tried removing/uninstalling all non essential drivers, extensions etc, and reinstalled/updated everything I can't work without to the latest versions. I've tried unplugging everything except 1 monitor, keyboard, mouse and USB authorization sticks. Nothing makes a difference. It's like there's a virus that progressively slows down my system, but I have found no virus on my system, at least via MacKeeper.
Here is my temporary solution: Every few weeks I reinstall Mavericks (right now 10.9.3) via the Apple online recovery system (Command-R on startup). The problem goes away completely and my Mac Pro is blazing fast again... For a few weeks, until audio performance deteriorates and I have to reinstall Mavericks again. Apple tech support originally advised me to reinstall Mavericks on top of itself, and I was really happy the problem was fixed, but I didn't know it would keep sneaking in over and over again.
This is the third time I have to reinstall Mavericks via online Recovery, and I am still baffled as to what could possibly get worse over time in this manner, and also specifically target audio performance! It's like some sort of cache is getting filled-up somewhere and overloading some of the computer's functions over time. Whatever this is, it gets reset during a reinstall.
If anyone has any ideas or hunches, they would be really appreciated!
PS: I've posted the same issue in the "Mac Pro" section to make sure I get the most coverage. I don't expect too many answers since not too many people have the Mac Pro yet and this is a targeted inquiry.

Make sure you got all the parts and pieces.

Computer to computer copy slows down over internal airport network over time

This is a strange problem but here goes...
Some useful background info:
I have recently successfully downloaded a 212MB file from a site on the internet through a new Apple Airport Express network I just created as a troubleshooting method in about 12 minutes or so and I don't seem to have any slowing down issues with internet connections to websites and downloads.
The issue I seeing with internal network copies:
When I try to copy files from an Apple PowerBook G4 running Leopard 10.5.2 to an iMac G5 running the same version of the OS, copies over the internal network exhibit a very odd behavior. The copy is from the Power Book G4's Public folder to any folder on the iMac.
The copy starts in The Finder just fine and seems to be going very fast as expected by an internal network copy but after some short arbitrary amount of time, the copy slows down, the estimated times grows slowly but consistently for the copy to complete and eventually the OS says there was a problem and the copy fails. There's no error number of message other than the copy couldn't be completed. As I mentioned above, the time to complete the transfer id initially estimated as a very short amount of time but eventually, the copy action hits a brick wall where it slows down further and further until it fails.
Other notes: the copy I've been attempting consists of files and folders that are of various sizes but I've tried it with small and large copies and this has worked fine in the past with Leopard and other, older OS' over the WRT54G's wireless network. I created the Airport Express network to see if that would solve this problem but it hasn't which makes me think the issue is with the router and not the wireless network.
Additional details:
Sometimes, the reported copy slowdown occurs at 5MB into the copy, other times it doesn't happen until it gets about 50MB into the copy. What's strange to me is, large file downloads over the Internet are just fine. There does appear to be some burst that degrades a bit over time but not like the internal network copy's speed which just drops off really quickly.
I have been successful in the past copying from Mac to Mac over this exact same router using the WTR54G's wireless network but I started having problems fairly recently and now the copy doesn't finish over the WRT54G or the Airport Express network that I recently created to see if the issue was with the WRT54G's wireless network settings or hardware.
There's plenty of free space on the machine that I'm copying to but this happens repeatedly when I try to copy from one computer running Leopard to another.
I don't think this issue is related to the Airport Express because I recently created a new network to test this issue called Bedroom Airport Express. Previously, when I'd been successful performing these types of transfers, I was using the LinkSys WRT54G's built in wireless capabilities and had no issues using Go To and entering the computer's IP address.
The router is still the WRT54G on ATT's DSL network using DHCP and there's no special config., other than that I had to re-IP the internal network to 192.168.199.1 for work related reasons but that's about it.
The MTU had to be increased to 1492 for the internet to work properly when I got my first WRT54G; an older version of this device that I replaced recently with a new one [although this copy worked with the new one as well prior to the issue I'm posting about coming up].
The firmware version of the WTR54G router is v8.00.2 and the Airport Express has been recently updated to the latest firmware available (this issue was occurring over the WRT54G's wireless network before the firmware upgrade to the Airport Express).
If anyone knows what if anything I can do to troubleshoot what the issue is, I would greatly appreciate the assistance.
This networking stuff is a bit of a black art to those of us that are dilettantes in this arena and I certainly qualify as a dabbler in the art of network configuration.
I've been using a LinkSys router for a long time with a Mac/PC internal network that connects to the internet and computers inside the internal network for many years now and have had few issues.
Thanks in advance,
Darin

I'm new to the Apple discussions, although not new to Apple computers and I've seen that this post has received quite a few views but no responses. Maybe someone could direct me to the right place to post this, if this is not that place, or, suggest some terminal tools that I could use to troubleshoot the issue with the Airport network or LinkSys Router I'm using [WTR54G v.8.0.0.x]? Thanks in advance for any assistance anyone can provide to a networking noobie.

ITunes sync bug causes space on iPod/iPhone to be gradually lost over time

This topic pertains to iTunes for Windows version 10.1.1 and most likely all prior versions. At the time of this writing 10.1.1 is the latest version.
I have clearly identified a bug with the procedure iTunes uses specifically to copy Music over to the iPod and iPhone units. A detailed description with steps to reproduce follows, but first the summary: Space is gradually wasted by iTunes erroneously copying certain tracks twice! The 2nd copy is not recorded in the itunesDB file, and space wasted on these duplicate tracks is counted under "Other" in the iTunes capacity screen. It is impossible to ever retrieve this space from the portable device without doing a factory restore on the Summary screen, which of course will also wipe out all your Apps, Videos, Photos, Music, etc at the same time. Hardly an ideal workaround!!
Details:
When several tracks are to be copied to the portable device; either an iPod or an iPhone, and I have successfully reproduced this on both an iPod nano 5th Generation and an iPhone 4, sometimes a track is accidentally copied twice while, one of the selected tracks isn't copied at all. The user will notice when this occurs, that during their sync, one of their songs just seems to be missing. Syncing again will then copy the track which was missed during the last sync, but unfortunately, the 2nd copy of the track that was erroneously duplicated remains. The track which is duplicated appears in the hidden folder on your iPod file system as both the AAAA.mp3 filename structure and the <track name>.mp3 file name. Oddly enough, when this bug occurs, the itunesDB does not associate to the AAAA.mp3 like it normally would, but to the <track name>.mp3 and the AAAA.mp3 file is just wasted space on your device which cannot be recovered without manually deleting this file (a task which is impossible on an iPhone without hacking the device).
It is easy to reproduce this. This is very obvious if you start with an empty, new iPod. Sync a bunch of tracks to your iPod (the more the better), in fact this cannot happen if you only sync 1 track at a time, then check to see if the number of tracks is equal to the number of tracks that should be there. i.e. did the sync seem to just miss 1 or 2 tracks?
Make sure "Enable disk mode" is checked for your device, and browse to (Drive Letter):\iPod_Control\Music\ and you will eventually find that exact number of files which have actual track names instead of the standard AAAA.mp3 type filename. Next, in iTunes, remove ALL songs and any other forms of audio (such as podcasts), from the device. Your music folder techincally should now be empty, but as you browse through the hidden Music folder in the device, you will stumble upon a couple of files that remain. These are the orphaned files I've been talking about.
The effect:
Over time, with repeated additions and removal of songs from one's device, these files accumulate. The iPod owner, none the wiser, will start to wonder why "Other" in the iTunes capacity display is continuing to grow. I was highly suspicious after cleaning out my iPod entirely, that "Other" was still showing 1.6GB!! I browsed through the filesystem wondering why which led me to discover tons of various music files in the music folder which shouldn't have been there (after all, iTunes shows no music stored on this device).
The Fix:
Some sort of bug is causing this erroneous duplicate copy to be generated, and then the database to actually reference the erroneous copy instead of the AAAA.mp3 copy. One workaround iTunes could actually build in some sort of enumeration function that scans all of it's internal F## folders in the Music folder looking for these orphaned files, and simply erase them if they are not contained in the itunesDB. Pushing out this type of behavior into a new iTunes release would also fix the problem for all the people who've already racked up GBs of wasted space as that space would suddenly become available again for apps, tracks, and other files.

Two steps forward - one step back.
Thanks to insight from others here I enabled disk use and went to [drive letter]/iPod/control/music
There I saw a long list of folders called F00, F01, F02 etc.
In my case there were 49 of them with roughly 400 files in each folder.
The bulk of the files were named ABCD.mp4 down to ZYXW.mp4.
In each of the fifty folders were, as predicted above, a handful of song files labeled as such - ie borntorun.mp3 or iseered.mp4
I opened each and every one of the folders, deleted the files with real names and synced the pod.
On my 120 GB the yellow "other" fell dramatically, down to under 1 GB. Which is under 1% of the total. Not great but acceptable.
So far, so good.
Now that I had fresh space I set about adding new songs to the pod.
Imagine my disappointment when I rechecked the F00 to F49 folders and saw that song name files had crept back in. Not as many, and I was able to delete them quickly and keep "other" under 1 GB. But still. It's like having crab grass or rodents.
Is there any hint that iTunes might address the underlying cause?
In the gripping process of deleting four or five files from each folder I noted that some specific files came up again and again. Just for laughs I'm going to delete and re-add those songs in case that helps.

Amount of key presses a user makes over time - BPM

Hi,
Im working on a small program that needs to get the amount of keypresses a user makes over time.

It doesnt seem to like me parsing int to string here:
String s = Integer.parseInt(i); Any ideas? or if youve got suggestions on another way to do it it'd be much appreiated.
Thanks!

Yikes, you've got that bit of code backward, there partner.
You use Integer.parseInt to parse a String into an int, not the other way around.
If you want to change an int to a String, do
String s = String.valueOf(i)or you can use the various formatters out there.

I ended up with 3 Apple IDs over time. How can I get it down to one account?

I ended up with 3 Apple IDs over time. When I sink my iPad, some apps won't sync because the app was purchased under a different account?
How can I get it down to one account and be able to sync all of my iTunes purchases (apps, music, etc.) on my iPad and iPhone?
This is driving me crazy! grrrr. :-)

Thanks for the reply.

Is ther a way to speed up a Mac? Mine has gotten slower and slower over time. When memory comes close to full would that have an effect on performance? Is there a way to determine unused programs/software to remove and free space?

Is there a way to speed up a Mac (similar to de-fragging on a PC)? Mine has gotten slower and slower over time.
When memory/disc comes close to full would that have an effect on performance? How should I determine what programs/software to remove and free space?

Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.

Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD disk icon and click on the arrow button below.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
Restart your computer normally and see if this has helped any. Next do some maintenance:
For situations Disk Utility cannot handle the best third-party utility is Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible.
Note: Alsoft ships DW on a bootable DVD that will startup Macs running Snow Leopard or earlier. It cannot start Macs that came with Lion or later pre-installed, however, DW will work on those models.
Suggestions for OS X Maintenance
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger. These utilities have limited or no functionality with Snow Leopard or later and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive.
Helpful Links Regarding Malware Protection
An excellent link to read is Tom Reed's Mac Malware Guide.
Also, visit The XLab FAQs and read Detecting and avoiding malware and spyware.
See these Apple articles:
          Mac OS X Snow Leopard and malware detection
          OS X Lion- Protect your Mac from malware
          OS X Mountain Lion- Protect your Mac from malware
          About file quarantine in OS X
If you require anti-virus protection I recommend using VirusBarrier Express 1.1.6 or Dr.Web Light both from the App Store. They're both free, and since they're from the App Store, they won't destabilize the system. (Thank you to Thomas Reed for these recommendations.)
Troubleshooting Applications
I recommend downloading a utility such as TinkerTool System, OnyX, Mavericks Cache Cleaner, or Cocktail that you can use for removing old log files and archives, clearing caches, etc. Corrupted cache, log, or temporary files can cause application or OS X crashes as well as kernel panics.
If you have Snow Leopard or Leopard, then for similar repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. Applejack does not work with Lion and later.
Basic Backup
For some people Time Machine will be more than adequate. Time Machine is part of OS X. There are two components:
1. A Time Machine preferences panel as part of System Preferences;
2. A Time Machine application located in the Applications folder. It is
    used to manage backups and to restore backups. Time Machine
    requires a backup drive that is at least twice the capacity of the
    drive being backed up.
Alternatively, get an external drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Carbon Copy Cloner
2. Get Backup
3. Deja Vu
4. SuperDuper!
5. Synk Pro
6. Tri-Backup
Visit The XLab FAQs and read the FAQ on backup and restore. Also read How to Back Up and Restore Your Files. For help with using Time Machine visit Pondini's Time Machine FAQ for help with all things Time Machine.
Referenced software can be found at MacUpdate.
Additional Hints
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
Check for applications that may be hogging the CPU:
Pre-Mavericks
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Mavericks and later
Open Activity Monitor in the Utilities folder. Select All Processes from the View menu. Click on the CPU tab in the toolbar. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file.

SSRS line chart showing premium change pct over time

Hi,
I have an SSRS report sitting over a cube. I'm building a Line chart to show premium change over time by producer (there are currently 6 producers). I have the Producer Name, Quarter/Year, and Premium amt.
I want to have the premium line trend based on the percentage of change from Quarter to Quarter. Quarter will be the X-Axis and percentage will be the Y axis. The premium for the first quarter should start at 100%. Each premium line for
the producer should then change up or down based on the change in premium per quarter. The end result should look something like this: Can this be done using SSRS?

SCEP date range reports change over time

Not really sure how to title this, but here is the scenario. I have altered a canned report to run the first Monday of every month and dump a Word file w/links into a folder. The alteration of this report is simply changing the end date to be -30 from today.
So I am getting a 30 day report of all computers that were infected. The report runs and looks to be accurate based on alerting I have setup. The problem comes when I take this report and start to drill down into the data using the links in the report. Let's
say my report shows a virus name with an infection count of 3. I can click on 3 and see a list of PCs that were infected....well not so much. If between the time the PC was infected and the time I look at the report, any of the 3 PCs were cleaned of the infection,
then they will not show up in the drilldown. So if a single PC was cleaned...the count still shows 3, but clicking on 3 only shows 2 computers now. This pretty much goes for any data on the main page.
So essentially the report is pretty useless to go back in time and see detailed info on the incidents since the status of every bit of info in that report has changed over time. I am not a SQL person, but I did have one of SQL team look at the database and
she can't see anywhere that she can pull archived data from. Any idea what direction I can point her in to get the type of reports I am looking for?

Yes, I know this is an old post, but I’m trying to clean them up. Did you solve this problem, if so what was the solution?

Skype using High levels of RAM over time

So recently i've noticed that Skype has been using increased levels of RAM over time. Before i think 7.1 it sat at a steady 170k or lower but since the recent update, it seems to scale all the way up to nearly using 80% of my RAM after being on for an hour. Is there a reason this happens or is it a memory leak issue?

Hi,
I'm having the same issue as you.
For my situation, with Windows 7 Ultimate 64bit, with 8 GB of RAM available, Skype use randomly from 400 Mb to 1.5 Gb of Ram slowing down all the PC..
I have to kill the Skype process for working well.
My SKYPE version is 7.3.0.101.
I need to resolve this problem (and, from my point of view, uninstall the newest version and install the older one is not a solution)
Thanks in advance
Andrea
