RE: [JBoss-user] Anyway to clean memory usage after run jboss?
I forgot to mention caching in my previous post. Look if your jboss uses large disk space (files), then part of it must appear as RAM cached, which also substracts from your free MEM. Think of going redhat 7.2 (REALLY STABLE, performer, (Beats FreeBSD 4.5 by 10%)) Think of going blackdown. We have had no problems which RH 7.2 and blackdown jdk1.3.1_02b-FCS. On the same machine we also run pgsql (which works all the time like a beauty), and also the world leader in memory leaks and bad performance Lotus Notes. [root@hermes jboss]# uptime 10:13am up 18 days, 23:08, 23 users, load average: 1.06, 0.99, 0.80 [root@hermes jboss]# (The last reboot were due to maintenance reasons and not a failure) See?? ___ Have big pipes?

Re: [JBoss-user] Anyway to clean memory usage after run jboss?
Are you using `free' command to report free memory? If you do it's a common error to look at the first line of report. `used' column there includes memory used for cache and buffers. Refer to the second line, the one that starts with `-/+ buffers/cache:'. Hope it helps. - Original Message - From: "Junjie Ding" <[EMAIL PROTECTED]> To: "Paul Cody" <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]> Sent: Thursday, May 16, 2002 8:33 PM Subject: RE: [JBoss-user] Anyway to clean memory usage after run jboss? > Hi Paul, > > Yeah, that's what I thought.

RE: [JBoss-user] Anyway to clean memory usage after run jboss?
Hi Paul, Yeah, that's what I thought. I killed all java process. I have no Timer or Threading Those memory is taken by nobody. Just seems like memory leak. As I remember, I didn't run into this problem when I was using Solaris 7. I just have this problem recently when I move to Linux. And there is another issue. I downloaded JBoss3.0 yesterday and tried to deploy my application there, just trying to compile and deploy. The memory usage goes up in the deploy process Any suggestion?

Re: [JBoss-user] Anyway to clean memory usage after run jboss?
To the person (thinking of ) having problems with his linux box: Can you please send an output from your, vmstat, ps, top, swapon -s ?? Can you read threaded apps ps output?? Are you sure your jboss shuts down properly?? (without leaving any threads running)?? If your app just fires an expensive DB operation, and then kills itself, or you shutdown jboss, the DB process will continue to eat up memory and cpu cycles. Thoroughly examine your system. Can you please be more specific of your setup?? Machine??, Database?? Also, upgrade to kernel 2.4.9-31 by redhat (also an upgrade to redhat 7.2 would be nice) (Note RedHat 7.3 is at stores). >From my experience it is much much safer,faster,BETTER to use the blackdown port than the one SUN gives.

Re: [JBoss-user] Anyway to clean memory usage after run jboss?
we had some problems with too many files being opened by the java process. you can find out the number of open files by giving. cat /proc/sys/fs/file-nr This wil give a result like 2448183 8192 where 2448 are the currently allocated file handles, 183 is the number of file handles are not used and 8192 is the maximum number that can be opened. so for the above number, the number of files used are 2448 - 183 = 2265. just try running a script that monitors these values. This might be one reason. Regards, Nagarajan.

I have the same problem and i work with SUSE 7.2 and JBoss-2.4.4_Tomcat-3.2.3. My application is same the petstore 1.1.2 but when i do several Tx., my server lost performance, lost network connection and need restart my machine Another person have the same problem?

Re: [JBoss-user] Anyway to clean memory usage after run jboss?
Junjie, Neglect if you already knew this. Just adding to what Paul said. Hit ctrl + Esc on your key board and you will be able to see all the processes running on your RedHat 7.1. Select all relevant java processes and kill them mercilessly :-) Rajesh On Thursday 16 May 2002 00:31, Paul Cody wrote: > What do you mean by "does not release memory"?

RE: [JBoss-user] Anyway to clean memory usage after run jboss?
What do you mean by "does not release memory"? You should never have to restart the machine, this is completely unnecessary. Just kill the java process that is running JBoss. If your application is not shutting down cleanly, think about any threads that you may be creating, esp things like java.util.Timer or interaction with the JMX Timer service. If necessary, you can run a debugger to see where the threads are waiting.
