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:
http://forum.java.sun.com/thread.jspa?threadID=643360&start=0&tstar…
regards

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
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.
No, xwiki.com is running on 3 real computers under Debian Sarge.
For the rest, i don't know.

New subject: [xwiki-users] 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.
