JVM Memory saturates and slows the server down

Hi all,
New serveur on W7. CF9 installed.
Every day, need to kill JVM process saturing up to 1,5Go to liberate memory.
How come that it does not come down. How to tune it in order to fit my trafic needs ?
Thanks for your help,

Hi,
Some more detail would probably help. Windows 7, CF9 and Java are 32 or 64 bit?
For bit check CF Java via Server Settings > Settings Summary > Java VM Name EG Java HotSpot(TM) 64-Bit Server VM
Sometimes Java matters are logged to ColdFusion9\runtime\logs\coldfusion-out.log . Any Java warnings or error messages in that log file?
JVM logging can be useful to know what is going on Java memory wise. I think there are many resources to search on how to do that tho if you want some direction reply the thread and I am sure to be able to point you to some links.
Indeed 1.5Gb is not a lot of RAM but it may not be apportioned well to suit your needs. Other than JVM logs it would also be interesting to know what Java version (A) you are using plus your JVM arguments (B)?
A) Server Settings > Settings Summary > Java Version EG 1.6.0_29
B) ColdFusion9\runtime\bin\jvm.config >
# Arguments to VM portion
java.args=-server -Xmx512m -Dsun.io.useCanonCaches=false -XX:MaxPermSize=192m -XX:+UseParallelGC
That should start to help you along, Carl.

DVDRW is Mega-Slow and slows the system down

Hi,
I have:
4 x SATA2 disks on the ICH7 (three in RAID 0, one as single disk)
1 x IDE DVDRW on the Secondary IDE port, set as slave
When I burned a DVD yesterday the sound started to slow, I thought it was the application. But when I try to install a game DVD, the same thing happens .. the sound becomes 'jittery' and most noticeably the DVD takes AGES (FOREVER) to read.
I checked the BIOS, JMicron is set to IDE. the rest is set to defaults.
I checked Device Manager, the only active channel (Secondary IDE) which was set to 'PIO ONLY'. I changed this to 'DMA if available' but it's still in PIO mode. I beleive it should be in DMA??
Should I be using a different cable? I'm using the MSI supplied cable at present.
Any assistance would be much appreciated!

You already have the latest stable release from MSI, but unfortunately lots of MSI customers have a problem with this BIOS version. There is a Beta release (1.6a) that BOSSKILLER posted earlier
http://www.ukshazam.com/download/bosskiller/7235v16A.rar
and it’s upgrading the Jmicron BIOS version too. You can choose between DOS or Windows flashing procedure. If you decide in Windows mode, download the latest BIOS version from MSI Live Update (Application that came with your Installation CD for keeping your MB up to date) and the file from the link above. After everything downloaded, go to Program files-Setup files replace only the bios file (extension .150) with the one from the link above(extension .16A), and run the MSIsetup file. Make sure that the Clear CMOS option is selected. For safety reason, make a recovery floppy and check for some setting in BIOS before flashing, so that you can configure the new version of the BIOS properly.
About the Widows drivers, Go to Control Panel – System- Hardware - Device Manager- “SCSI and RAID controllers” – right click on Jmicron- Uninstall.
Then: Control Panel- Add or Remove Programs – JRAID-uninstall.
Restart your computer, and when you’ll be prompt that “Found New Hardware”, click cancel on the “Found New Hardware wizard” and install the drivers that I’ve posted earlier (double click on the setup file).
Try with the drivers first, and if the installation is successful under DVD/CD Rom Devices you will notice that the drive is recognized as SCSI cD/Rom Device.
Good Luck

There is a Virus in my Mac, how to remove it, whenever I open a certain app it comes and slows the computer down, how to delete it?

Please Help Me

It is possible, but extremely unlikely you have a virus. It is more likely to be related to corrupt preference files for the offending (lagging) apps. These preference files can be found by opening a Finder window, select the hard disc > Library > Preferences. The file will be 'com.apple.(app name).plist' without the inverted commas and including the app name, safari, skype, etc. You can delete these files. Delete them, empty the trash and restart your computer.
You should also run a disc maintenance app like, Onyx. Install it, open it and select 'Automation'. This will clear all your caches, run maintenance scripts and repair permissions in one click. It is a free app. NB: When you open Onyx you are prompted to run some disc checks. You can cancel these. You are also given a warning about backing up your data, which you should be doing anyway.

Firefox.exe uses too much memory slowing the computer down, what can be done?

This doesn't happen every time I am using the browser, maybe half of the time. When it does happen it takes a long time for it to clear up. It can slow the computer down even after I have exited out of the program, maybe still not responding because of high memory usage. Is there anything I can do to get Firefox to run smoothly?

Some updates are better handled by Internet Explorer or the built-in updater, such as any updates from Microsoft's Windows Update or Office Update systems. (These systems are not compatible with other browsers.)
You can use the "all systems" page to download a full installer and then copy it over to your XP system.

I have a 1st generation time capsule and an extreme b/g. Is the extreme slowing the network down

I have a 1st generation time capsule and an appe extreme b/g. Is the extreme slowing the network down? Should I dump it an get the new n version?

yes it is likely to be slowing down the network because you are using 802.11b/g
from what i recall with b/g a slow client can slow down the entire network to that clients speed.
this was the major improvement with 802.11n and Mimo. each client can be connected to the access point without affecting your speed to the rest of the network
its reccomended to get all new "N" equipment if you have the budget for it. some of those old airports and time capsules can still be worth something on amazon marketplace so you might be able to sell them
if you want to create / join / extend a netwowrk your going to probably need all "n" based equipment.
buy the new 4th generation time capsule or the new 5th generation airport they have better stronger radios
in the mean time configure your base station router to a high multicast rate, so it will prevent devices connecting to it at 1-2 mbps speeds and slowing down your network
if you have an apple care covered mac remember the airport / time capsule rule. all airports and time capsules purchased 2 years before you bought your mac to the 3 years of apple care covers them. if you do not have apple care then the standard warranty applies

I've been getting the same message for like an hour now. Since everything was working fine a few hours ago, and nothing changed on my end before it stopped working, I'm guessing it's something on Apple's end. They probably already know about it by now, and are hopefully working on fixing it, so there's probably not much we can do but wait for them to fix it.

In the Quicktime 7 A/V controls, how fast is the 2x playback really because it isnt twice as fast. I shot a music video on the 2x setting and when we slowed the footage down to half time, it did not line up.

Unable to initialize the Microsoft Exchange Information Store service because the clocks on the client and on the server machine are skewed

Each time I restart this exchange server, the Information Store and System Attendant don't start. If It try to manually start the services, I get the follow errors:
Event ID 5003:
Unable to initialize the Microsoft Exchange Information Store service because the clocks on the client and on the server machine are skewed. This may be caused by a time change either in the client or the server machine, and may require a reboot of that machine. Other than that, verify that your domain is properly configured and is currently online.
Event ID 1005:
Unexpected error The clocks on the client and server machines are skewed. ID no: 80090324 Microsoft Exchange System Attendant occurred.
The clocks on the domain controllers and the exchange server are set to the same time zones. As well, all three clocks are in sync down to the second. Any ideas on what's causing this and how to fix it?

Run this Command from the Exchange Server
Net time \\ADServerName /Set
and confirm the action,
and then you need to restart the service
Microsoft Exchange Active Directory Topology Service
and confirm you are not getting the Error 4001 in the event Viewer.
Thank you, it resolved my issue after being sweating looking for solution.
How can I prevent this from happening? I cannot restart services on each server reboot nor lose 5 years of my life!!!

Firefox freezes if I try to initiate a remote console session with the Netware 6.5 server I am connected to. I can force quit, re-initiate Firefox, re-authenticate and I'm able to successfully start a remote console session and acquire the server console.

Hi Mac Attack,
My computer will not disconnect from the internet. It seems to find a clone router and continues even when I shut down and unplug my my own home iy
Your main question was 'chopped' in the title. Please reply in the body of a reply box with the full question and anything you have tried. And no, the long report was not helpful .
If the same website is opening each time you launch a browser (Safari?) hold down the shift key as you launch to prevent previous pages from opening.
Have a look at your settings in Safari > Preferences. Especially General and Privacy.

I cannot connect to my game center account October 31, 2013. It's said that "Could not connect to game center server"... is the Server down? could it be fixed quickly

I cannot connect to my game center account October 31, 2013. It's said that "Could not connect to game center server"... is the Server down? could it be fixed quickly I play Clash of Clan and I really upset when this problem happen @@!

This happened to me as well. **Warning: The following steps will remove all network passwords from your phone and you will have to re-input them. Unfortunately, this is unavoidable**
To resolve, I went to Settings > General > Reset > Reset Network Settings and accept the Reset Network Settings option.
Afterwards, I was able to log into the Game Center without a problem.
Cheers.

I cannot find this 300GB "Backup" in the Finder, only in the Storage info when I check "About This Mac".
You are probably using Time Machine to backup your MacBook Pro, right? Then the additional 300 GB could be local Time Machine snapshots. Time Machine will write the hourly backups to the free space on your hard disk, if the backup drive is temporarily not connected. You do not see these local backups in the Finder, and MacOS will delete them, when you make a regular backup to Time Machine, or when you need the space for other data.
See Pondini's page for more explanation: What are Local Snapshots? http://pondini.org/TM/FAQ.html
I have restarted my computer, but the information remains the same. How do I reclaim the use of the 300GB? Why is it showing up as "Backups" when it used to indicate "Photos"? Are my photos safe on the external drive?
You have tested the library on the external drive, and so your photos are save there.
The local TimeMachine snapshot probably now contains a backup of the moved library. Try, if connecting your Time Machine drive will reduce the size of your local Time Machine snapshots.
