Hello,
Cocoon 2.1.6 is running on Fedora Core 1, 512mb ram with celeron 2.4ghz.
I'm not sure what is the reason of this problem. When I try to
simulate high traffic with ApacheBenchmark tool then
java.lang.OutOfMemoryError
does not happen. But after few hours(5-10) of running on real
traffic(1-2 requests per second) Cocoon/Tomcat hangs up and start to
fill catalina.out with error message presented below. I'm planning
to get on better server from 1st of January, but before that I would
like to fix this problem. Tell what additional information do I have
to provide for You, to help to recognize this problem.
I really need Your help. We expect higher traffic on our site in next week, so
the situation is critical.
