RE: [xwiki-users] Hs_err_pid XWiki 0.9.840 + tomcat 5.5.9 + vm1.5.0_06
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&tstart=0 regards -----Original Message----- From: Yoav Shapira [mailto:[email protected]] Sent: Mittwoch, 15.

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 On 3/15/06, jeremi joslin <[email protected]> wrote:

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.

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.
