java out of swap space error
Hi,
I am getting the following error in the geronimo logs for my webapp:
Exception in thread "CompilerThread1" java.lang.OutOfMemoryError: requested 32764 bytes for ChunkPool::allocate. Out of swap space?
I did some research and added the following java_opts in geronimo.sh:
JAVA_OPTS='-Xms512m -Xmx512m -Xss128k -XX:PermSize=128m -XX:MaxPermSize=128m'
This virtually eliminated the problem but I am still seeing it occasionally. Do I just need to tweak these memory settings or is there something else going on? I don't get this error during periods of particularly high usage so it is a little puzzling. I'm running geronimo 1.1.1 with jetty, java 1.5.0 on freebsd 4.
Thanks,
Theo

From memory I think this means Solaris is out of swap space. I think
you will find the problem will go away if you add another swap file.
Additional swap space can be allocated without having to bring the
system down. See:
http://docs.sun.com/app/docs/doc/817-5093/6mkisoq83?q=swap+file&a=view

John

I just started seeing this error today pretty consistently on my Geronimo
instance as well. There are some Sun bug reports that describe this issue,
but I have not found any definitive cause yet. The HotSpot compiler seems
to have some trouble allocating a chunk of space during bytecode
compilation. I've seen a suggestion that HotSpot can be disabled with the
-Xint property which would force it to run in interpreted mode, although
there would be a performance hit with this.
The size of the heap on my own server was not overly large when I got this
error, so it's kind of strange. Right now I'm working on trying to fix
this issue, so if I find anything out, I can let you know.
Similarly, if you manage to solve this issue, let me know. :-)
