Hs_err_pid XWiki 0.9.840 + tomcat 5.5.9 + vm1.5.0_06

Leonard Lin-3
Hi

I'm using Xwiki 0.9.840 with Tomcat 5.5.9 on java-vm 1.5.0_06
(Redhat linux) and experience regular crashes of my JavaVM.

It happens on average once a month.

I searched the net without any usable explanation.
Previously I was using java-vm 1.5.0_05 hope the upgrade to 1.5.0_06 would solve it, but it didn't

At the end I dumped the most recent hs_err_pid-file found on the system.
However they are all the same stating that the problematic frame is [libjvm.so+xxxx]

Does anyone have similar experiences?

Thanks in advance

Leo

Re: Hs_err_pid XWiki 0.9.840 + tomcat 5.5.9 + vm1.5.0_06

zuzur
Hello Leonard,

i have experienced the same kind of problem on the XWiki.com farm,
which is memory/gc intensive. Can you elaborate on your tomcat
configuration ?

I'd also like to know what parametes you use for tuning the GC
-Xmx/-Xms ? The heap figures you sent seem very low to me, which would
explain the problem if you stress the server.

Anyway, having the VM crash is a VM bug and we can't do much about
this specific except report it to SUN and work around it :-(

RE: Hs_err_pid XWiki 0.9.840 + tomcat 5.5.9 + vm1.5.0_06

Leonard Lin-3
In reply to this post by Leonard Lin-3
Hi

The options used are:

JAVA_OPTS="$JAVA_OPTS "-Dfile.encoding=UTF-8
JAVA_OPTS="$JAVA_OPTS "-Xmx256M
JAVA_OPTS="$JAVA_OPTS "-Xms256M

What options do you use?

Well you're right that it's a VM-crash, however it usually happens when something goes wrong in the
Code. I suspect some ressource leaks in xwiki. It uses lot of memory, and isn't really fast.

I don't know if it's related, but the xwiki-sites is often offline, I suspect for a long time already that
they have the same problem.

Thanks for any help, regards

Leo

Subject: Re: [xwiki-users] Hs_err_pid XWiki 0.9.840 + tomcat 5.5.9 + vm1.5.0_06

Hello Leonard,

i have experienced the same kind of problem on the XWiki.com farm, which is memory/gc intensive. Can you elaborate on your tomcat configuration ?

I'd also like to know what parametes you use for tuning the GC -Xmx/-Xms ? The heap figures you sent seem very low to me, which would explain the problem if you stress the server.

Anyway, having the VM crash is a VM bug and we can't do much about this specific except report it to SUN and work around it :-(

RE: Hs_err_pid XWiki 0.9.840 + tomcat 5.5.9 + vm1.5.0_06

Ah sorry, didn't see that you're running the xwiki.com website. ;-)

Subject: RE: [xwiki-users] Hs_err_pid XWiki 0.9.840 + tomcat 5.5.9 + vm1.5.0_06

Hi

The options used are:

JAVA_OPTS="$JAVA_OPTS "-Dfile.encoding=UTF-8 JAVA_OPTS="$JAVA_OPTS "-Xmx256M JAVA_OPTS="$JAVA_OPTS "-Xms256M

What options do you use?

Well you're right that it's a VM-crash, however it usually happens when something goes wrong in the Code. I suspect some ressource leaks in xwiki. It uses lot of memory, and isn't really fast.

I don't know if it's related, but the xwiki-sites is often offline, I suspect for a long time already that they have the same problem.

Thanks for any help, regards

Leo

Hello Leonard,

i have experienced the same kind of problem on the XWiki.com farm, which is memory/gc intensive. Can you elaborate on your tomcat configuration ?

I'd also like to know what parametes you use for tuning the GC -Xmx/-Xms ? The heap figures you sent seem very low to me, which would explain the problem if you stress the server.

Anyway, having the VM crash is a VM bug and we can't do much about this specific except report it to SUN and work around it :-(

RE: Hs_err_pid XWiki 0.9.840 + tomcat 5.5.9 + vm1.5.0_06

Leonard Lin-3
In reply to this post by Leonard Lin-3
Hi

Are you running xwiki.com on a virtualized system such as VMWare?
One of our programmers suggested, that it might have something to do with
VMWare (in our case) because of the SIGSEGV issued,
Pointing to either errornous implementation in javaVM or
failing Hardware.

regards

Leo

Ah sorry, didn't see that you're running the xwiki.com website. ;-)

Subject: RE: [xwiki-users] Hs_err_pid XWiki 0.9.840 + tomcat 5.5.9 + vm1.5.0_06

Hi

The options used are:

JAVA_OPTS="$JAVA_OPTS "-Dfile.encoding=UTF-8 JAVA_OPTS="$JAVA_OPTS "-Xmx256M JAVA_OPTS="$JAVA_OPTS "-Xms256M

What options do you use?

Well you're right that it's a VM-crash, however it usually happens when something goes wrong in the Code. I suspect some ressource leaks in xwiki. It uses lot of memory, and isn't really fast.

I don't know if it's related, but the xwiki-sites is often offline, I suspect for a long time already that they have the same problem.

Thanks for any help, regards

Leo

Hello Leonard,

i have experienced the same kind of problem on the XWiki.com farm, which is memory/gc intensive. Can you elaborate on your tomcat configuration ?

I'd also like to know what parametes you use for tuning the GC -Xmx/-Xms ? The heap figures you sent seem very low to me, which would explain the problem if you stress the server.

Anyway, having the VM crash is a VM bug and we can't do much about this specific except report it to SUN and work around it :-(

No, xwiki.com is running on 3 real computers under Debian Sarge.

Re: Hs_err_pid XWiki 0.9.840 + tomcat 5.5.9 + vm1.5.0_06

YoavShapira
Hola,
As someone with Tomcat (though not XWiki) experience, 99% of the time
these SIGSEGV faults result from a problem with the JVM installation
missing required OS patches.  Start at
http://java.sun.com/j2se/1.5.0/install.html, pick the edition you're
installing, and click on the Linux Notes link from the resulting page
for required patch levels for things like glibc.  I hope that helps,

Yoav

Hi Yoav

Thanks a lot for your hint.
As far as i have seen the problems stated on the sun-website are concerning
Old kernels or older glibc

We use
Kernel: 2.6.9-11.ELsmp
glibc: 2.3.4

Though the following link seems to me heading into a similiar direction:

Hola,
As someone with Tomcat (though not XWiki) experience, 99% of the time these SIGSEGV faults result from a problem with the JVM installation missing required OS patches.  Start at http://java.sun.com/j2se/1.5.0/install.html, pick the edition you're installing, and click on the Linux Notes link from the resulting page for required patch levels for things like glibc.  I hope that helps,

Yoav

Re: Hs_err_pid XWiki 0.9.840 + tomcat 5.5.9 + vm1.5.0_06

Hey Leonard,

yes i'm taking care of xwiki.com. Yes recently it has been a real
PITA, most of the instability problem were due to comment spammers
hitting us hard. Since last saturday we are running mod_security on
our frontend servers and i do not have to check every hour if one of
those assholes took us down again ! what a relief !

(take care with the latest gotroot rules for mod_security, our apache
ate all available memory then had to be killed - blacklist.conf is too
big, i don't use it anymore)

I'll check the system requirement route, but we don't experience VM
crashes very often.

One hint about your particular VM crash. As every thread appears to be
locked when it happens, it seems to be garbage collecting related, and
i'd investigate tuning the new generation and related stuff. I've got
this already on my TODO list and will let you know the outcome.

I posted a note about this on my weblog
(http://www.arzur.net/index.php?English) where i suggest every
spammers taken to courts should pay a check to the OSS anti-spam
project of his choice. Another way of financing OSS. Most of the good
tools in this field are open source anyway. SpamAssassin, SpamBayes,
mod_security, gotroot.com ... come to mind.
