Incremental Garbage Collector is halting my server for MINUTES at a time.

I have a Java server which services hundreds (currently 300-700 on average, target of 2000+) of simultaneous client connections, with a staggering number of long lived (but not permanent) objects.
The docs for incremental garbage collection state: "The incremental garbage collector, which is off by default, will eliminate occasional garbage-collection pauses during program execution." This is NOT true in my case. During peak load, the Server halts occasionally (once an hour or more) and entire MINUTES tick by. Average wait time is 2.5 - 3.5 minutes, the highest I have seen is 4 minutes, 10 seconds. This is entirely unnacceptable.
The server is on Red Hat Linux 6.2, kernel 2.2.14-5.0, with a gig of RAM. My current command line options are
java -server -Xincgc -Xms256M -Xmx900M
And I have just added -verbose:gc to help analyze the gc performance. I have read the gc tuning guide at http://java.sun.com/docs/hotspot/gc/index.html but still feel rather clueless about what is the optimum setup for my particular application.
I will of course start experimenting, but I was hoping to find a "wise old elf" who might give some useful pointers to accelerate the process, seeing as how the Server is already running in a production capacity, time is critical.

Are you using a Java application server like Tomcat, Dynamo, WebLogic etc. ?
In that case consider running several server instances on the machine, with the applicationserver's software load balancer. Find the amount of RAM allocated to the heap per serverinstance where garbage collection runs takes a couple of seconds, and don't allocate more than this to each server. Start as many servers as you have available RAM for.
This is the approach recommended by application server vendors such as BEA http://edocs.bea.com/wls/docs61/perform/JVMTuning.html and ATG.
A side benefit of this approach is that in case you get more concurrent users than your computer can handle, you already have the setup for spreading the load over several computers.

You can see that between 12:48am and 9:38am, the Server is pausing for a combined total of TWELVE MINUTES! Often for 2 whole minutes at a time, during which the Server is completely unresponsive.
I have read Sun's GC tuning guide at http://java.sun.com/docs/hotspot/gc/index.html but it is not much help:
It says "Pauses can be minimized by using a small young generation and incremental collection, at the expense of throughput."
Well, I AM using incremental collection, and the young generation is the default size, which is quite small I believe. (32 MB max?)
It also says "Unless you have problems with pauses, try granting as much memory as possible to the JVM. The default size (64MB) is often too small."
Well I DO have problems with pauses, but I HAVE to allocate a ton of memory. The Server must support hundreds of simultaneous users, each with hundreds of K's of personal, dynamic, temporary data.
It also says "Unless you find problems with excessive major collection or pause times, grant plenty of memory to the young generation. The default MaxNewSize (32MB) is generally too small."
I AM having problems with excessive major collections and pause times, so according to this I should NOT grant more memory to young generation (eden).
What am I left with? Nothing! I am totally out to lunch here. The box this is running on is a dual P3-600 with a gig of RAM and Red Hat 6.2, with Sun JRE 1.3.1_02. My startup command line options are:
java -server -Xincgc -verbose:gc -Xms256M -Xmx900M
What should I do? The Tuning guide essentially says to screw around with generation sizes, but none of its specific tips seem to apply to me! This is a production server and I am worried about making things worse by playing around, so I was hoping someone out there might have some experience with this and concrete advice before I just start messing around with the memory map. Should I increase the young generation size? Decrease it? Something else altogether? HELP!

With default settings, I am getting horrible performance, under peak load, 25%-50% of server time is being spent with GC, approx. 11,000 minor GCs per hour! And a Full GC every hour or two which takes up several minutes. On average, I am losing 13.09 minutes per hour due to minor GC, and 54.5 seconds to major GC.
I tried your settings, Chuck, and they seemed to be working beautifully at first... minor GCs were now occuring once every few minutes for a couple seconds, instead of 3 times per second for a tenth of a second. Minor GC were now taking 1.06 minutes per hour instead of 13.09, more than a 1300% improvement!
HOWEVER...
After 7 hours, the Server started getting REALLY slow for no apparent reason. It seemed almost as if reading from sockets was suddenly becoming extremely time intensive. Then I got a HUGE minor GC that took 25.6 seconds. [GC 507410K->478034K(551296K), 25.6328459 secs], then a couple minutes later, the Server CRASHED with this output:

Yummy. Signal 11's really make my day fun :(. I tried restarting the Server, but it crashed again in the same way 15 minutes later. Then I switched back to default settings and it has run fine all weekend.
The Sig11 makes me think either our C lib is buggy (our Linux distro is getting a bit old), or we have a physical memory problem. Odd that it only shows up when I tried your new settings though...

Galaxy Note II Unresponsive for minutes at a time

I'm on my 3rd galaxy note 2. My first one had an overheating problem that caused the battery to last for 2 hours even though it was idle. They ended up replacing it for me. My 2nd one was actually perfect. I had zero problems with it for nearly a year until the day after the 4.3 update, the screen went off and never came back on. I just got my replacement about a week ago and I'm having an issue with the screen becoming unresponsive for minutes at a time.
I factory reset the phone yesterday thinking that maybe I had a rogue app installed but it seems that any time I try to launch a game or if I try to browse the internet while an app is updating, the phone is unusable for a few minutes. It's like it can't multitask. Eventually it'll come back with the phone at my home screen with my background image gone, but eventually it comes back too. It's similar to when windows explorer crashes and it reloads. I'll go through the same process for 2 or 3 more times before the game finally launches or the internet browser is finally usable.
Before I call this phone defective, I was wondering if it's a problem related to 4.3 that I should be aware of? I installed a monitor and it looks like with no apps open, from a fresh reboot my ram is 50-80% used which doesn't leave much room for opening apps or playing games. I even installed a virus protection and scanned for a virus (i know viruses on smartphones is a stretch) and it returned no issues.
Any ideas? I could factory reset it again, but I just did that last night and it didn't help still having the same problem with very minimal apps reinstalled. One note, I factory reset it with the restore from backup functionality turned off, so the apps I did install were from scratch, not my google account.

I decided to call in. I tell the rep my problems and he tells me to launch the phone in safe mode. Done. I could reproduce the issue. It then says wifi unstable. The phone freezes with wifi on. Tells me to turn the wifi off. No more freezing while in safe mode, I guess wifi is the problem didn't think that was an issue before. He tells me that wifi issues have been reported but none of those issues cause the phone to freeze, he said that samsung told them to tell customers to turn that feature (ie: wifi) off until the next software update. He said samsung is working on a fix for the wifi issues but said there's no eta. I asked him for his gut feel and he said phones that are newer than 18 months normally get priority, given that the note 2 was release in november of 2012 and we're in 2014, that he estimated 3-4 months for the next update. I know I can't hold him to that but even if he's right, I have to leave wifi off for 3-4 months?...Now to the best part, "Since there is no freezing with wifi off in safe mode, and in safe mode the phone behaves in the state samsung designed it to be in, I've determined that it's not a hardware or operating system issue, so there's nothing I can do for you. I'm sorry I couldn't send you a new phone or resolve this problem for you, I hope you find a solution for the software issue you're having, good night."
Rather than get mad I realized I wouldn't get anywhere with him so I didn't try to push the issue. I know I have unlimited data so it's not that big of deal, but wouldn't you consider the phone not working regularly with wifi turned on a hardware or os system problem? It's not like I can uninstall and reinstall wifi. The drivers are embedded in the system and since it's a refurb phone, who's to say that the parts that were refurbed are really factory oem?
Now I'm stuck with a phone that is unusable randomly for 3-5 minutes using the phone normally with the mobile network/wifi because the agent didn't consider the problem to be hardware or os related and the only way to keep it from having issues is to not turn on wifi and keep the phone in factory default settings.
I'm not going to threaten to leave or go somewhere else because it would serve no purpose, maybe that's why there was no attempt made to help me other than saying no from the beginning of the conversation, but in my 15 years of being a loyal customer, you would think "i hope you find a solution on your own" would be after sending me a new device if the problem persisted.

Fontd process causing Mac to lock up for minutes at a time

Here is a problem and also the solution, (in case you have the same problem):
My Mac (running OS X Lion) was exhibiting a problem whereby it paused for minutes at a time; the mouse moved, but no applications could respond (and they all showed the spinning beachball). Turned out to be a rogue ‘fontd’ process. This is how I fixed it.
So the symptoms were that occasionally applications would stop responding for a minute or two. This would especially happen when I launched a new app or browser window, and also occurred when I logged in after rebooting: it would hang with a near-empty screen, slowly opening my apps, waiting a(n agonising) couple of minutes between each one.
To cut a long story short (long version here: http://dysphoria.net/2012/02/18/mac-keeps-pausing-fontd-run-amuck/ ), the solution was to flush the font cache, as described in a Macworld article here: http://www.macworld.com/article/139383/2009/03/fontcacheclear.html
At the command line:
atsutil databases -removeUser
atsutil databases -remove
atsutil server -shutdown
atsutil server -ping

Why does iTunes freeze up for minutes at a time when modifying INFO (CMD-i) ? My files are not corrupted after it is done like many other threads i have readed. Sometimes it's changing the title of a movie or editing the season and episode number of a TV show ect.....

Yup same here
I am running the latest iTunes, the latest updates to the OS and on an iMac 3.4GHz Quad core i7 with 8GB of RAM and the music stored on local HDD.
Still locks up iTunes for between 2 minutes up to 20 minutes.
Really annoying.
If you find a fix please, please let me know, I have just been throwing hardware at it with no joy at all

IPhone 5s screen freezes for minutes at a time after iOS 8.0.2 install

My previously perfect iphone 5s has just been updated to iOS 8.0.2 and now for minutes at a time the touch screen doesn't work. The buttons do, but not the screen. It then comes back to life for a minute or two before it stops working again. Anything I can do? Thanx

Hey there Shortos,
It sounds like your phone touchscreen is not consistently working for you after updating to iOS 8. I can see how that would be pretty frustrating. It sounds to me like this could be a software issue or an issue with the screen itself. I would start with the troubleshooting in the following article to help troubleshoot the screen itself:
iPhone, iPad, iPod touch: Troubleshooting touchscreen response
Restart your device
Hold the On/Off button until "slide to power off" appears. Slide to power off your device. When it is off, press the On/Off button to turn it back on.
If you can't restart your device, reset it by pressing and holding the Sleep/Wake button and the Home button at the same time for a least ten seconds, until the Apple logo appears.
Clean the screen with a soft, slightly damp, lint-free cloth.
Avoid using the device while wearing gloves, with wet hands, or immediately after applying hand lotion.
If you have a protective case, or if you are using a plastic sheet or film on the display, try removing them and testing the device without it.
If that does not resolve the issue, I would next quit all the running apps on the device:
iOS: Force an app to close
Double-click the Home button.
Swipe left or right until you have located the app you wish to close.
Swipe the app up to close it.
When you have done that restart the device and test the issue again:
iOS: Turning off and on (restarting) and resetting
Thank you for using Apple Support Communities.
All the very best,
Sterling

Connection drops for minutes at a time

Hi there.
As I said in the title, the connection to the internet drops for minutes at a time although I am still connected to Airport Extreme. It has and can be down for pu to 20 minutes, with the only way of solving it that I see to be renewing the DHCP licence. Even when I do this, it can take up to 5 minutes to start working again.
When the error is happening, in the assist pane of the Network settings, all the little lights are green up to ISP. Internet and below are orange.
Any ideas?

Any?

Shared external HDD minimum 2TB (or server) for 4 Macs with time machine backup?

I work in a small design studio running 4 macs we need to put all of our work on one central harddrive that everyone can access. But then we would also like one Mac with an external harddrive attached to back up the contents of that shared drive. I have spoken with the people in the business centre But they dont seem to understand what I am trying to do.
I appreciate any ideas you may have.
So far what i have been sugested by the business centre is airport exterme with external HDD attached. But when i ask about using time machine to back up that HDD they get confused.

I have found on my server log the following information:
07/29 13:33:13 WDShareSpace daemon.warn afpd[3105]: volume "WD_Backup" does not support Extended Attributes, using ea:ad instead
What is the "Extended Attributes" and how do I use "ea:ad" instead?

My Macbook Pro has started freezing or 'hanging' for minutes at a time.

Cannot figure out what has caused this. Been doing it for three weeks now. Have re-installed OSX, wiped and restored from Time Machine but no difference. I would very much appreciate any help with this...... Console log looks like this:

Since yesterday, I have been seeing "bookmark syncing in progress" on the status bar for minutes at a time, and the browser becomes almost useless as it freezes.

At some point, I'll see 'bookmark syncing failed', and the browser then acts normally, BUT the behavior is cyclic. I uninstalled 7.0.1 and installed 3.6.20 and the behavior continued. I disabled sync in both installs and the behavior continued. I even deleted the sync server URL in about:config and the behavior *continued*. Oddly, the logs don't show any failures, and report success every time.
BTW, the bug-reporting procedure needs serious clean-up. It is very difficult to navigate the maze. And the help files are atrocious.

That maybe fixes some issues, but not this one. This one has to do with Sync and is getting seriously annoying.

Firefox 9.01 hangs for minutes at a time on three different computers.

I upgraded all three of my machines to 9.01. All XP service pack 3. Before, if there was a stall in the data flow, I could access the other tabs or do other tasks.
Now if the modem hangs, I get a "not responding" from Firefox, which might last for 5 minutes.
I started watching my DSL modem, and realized that the data light was not blinking at all.
It was as though Firefox was not even pinging for data.
For a while, then the modem would go quiet and it would hang again.
I ran visualtrace to see where the blockage was, and as soon as I started the trace, the modem started downloading data, but Firefox does not see it.
The trace shows no blockages.
I used to open 4 or 5 tabs at once in the morning, and read them as they download.
Now, the browser is stalled until they all download, and that might take a long time, because no data is flowing.
If I click on the close button, the browser closes instantly, with no warning about closing tabs.
When I reopen it, it treats the close as a crash and give me the option of which tabs to try to reopen.
I am using Kaspersky but disabling it does not help.
I'm sure you will find the bug soon, and I will keep checking for updates.
I downloaded Chrome to have something to use while I waited, but saw a place where I could download version 8,X of Firefox. I will revert back to it at my office because I need a usable browser. I will try to limp along with 9 on my two personal machines, unless it takes too long.
I have the copy of 8.X on a thumb drive just in case.
I hope you find this bug soon. I want to stay current in my browser, and Chrome sucks.

Check and tell if its working.

Since installing Mountain Lion my computer freezes up for minutes at a time.

I can't even force quit. It seems to freeze often when using Chrome. I just got a freeze up when I tried to open a new window in Chrome.
I have already try Disk Utility in Safe mode which fixed a lot of permissions errors, but I am still having the freezing issues. Below is the log from the latest Chrome error:

Please help.

That maybe fixes some issues, but not this one. This one has to do with Sync and is getting seriously annoying.

I installed itunes 11. It takes 100% of cpu and GUI is not responsive for minutes at a time. Keystrokes are lost in the search box because of this. This worked fine in previous release. I have 4300 albums and 70k songs.

I have an itunes library of 4000+ albums and 70k+ songs. Worked great until itunes 11 today. Now, when ever I go to the search field and type 1 character, I go to 100% CPU busy and all the other characters are lost. "itunes not responding" for a couple of minutes.
Also happens when I am importing a CD from physical media, and I switch to music and try and find another album. Gui becomes unresponsive and activity monitor ends up reporting "Itunes (not responding)".
How go I go back to the working itunes?

Thanks. That was it I don't know why it got changed during the upgrade to iTunes 11.
However, it still takes 5-10 seconds for this menu to appear, with the cpu at 100% one core. Seems like iTunes should support multi-threaded/multi-core processing, especially for the GUI.

Incremental Garbage Collector is halting my server for MINUTES at a time.
