OX 5 errors

[Adrian von Bidder]

Hi,

Recently, we've started to see frequent out of memory errors in Tomcat --
see below.  Usually after about 4 days running (~100 users, with about 20
to 60 sessions open simultaneously.)

This is on a OX 5 + SLES 9 system; current work around obviously is to
reboot daily, but this is not really acceptable.

Where can I look next?  What parts of the configuration should I look at /
tweak?

Any more data required?

Hi Adrian,

See the knowledge in Open-Xchange portal about "Tomcat work around" and
"registered.request=false"

Best regards,

Thanks, will try.

For the peanut gallery and google, since the portal's search function did
not help me at first (seems to be case sensitive search, or a broken full
text index?  In any case, I *did* search for OutOfMemory and this article
didn't come up :-(

in /usr/share/tomcat/bin/catalina.sh
  -> JAVA_OPTS=" -server -ms20M -mx512M "

(important is the -mx value.  We used 1024M since the machine is big enough)

And in /etc/tomcat/base/jk2.properties
  -> request.registerRequests=false

which is said to avoid triggering a memory leak.

cheers

This is what open source software is all about: creating knockoffs and
giving them away, destroying the value of whatever the other guy is
selling.
