more out of memory on 2.3.1
Hello,
I'm trying to track down the root cause of this:
"Exception in thread "CompilerThread1" java.lang.OutOfMemoryError:
requested 134217744 bytes for Chunk::new. Out of swap space?
"
This occurs about every hour, on a server running a fairly small amount
of users. I set the JVM Xmx to 512mb. Before I try setting it to
1024mb (the max phys capacity) is there something else I should be
looking at?
Thanks,
Jim

Thanks for the leads...
I upgrade the JRE to 1.6 (opensuse 10.3) and the problem has not
manifested itself since.
Should it happen again, I'll post more details in case any else runs
into similar circumstances

First thing first: if you can upgrade your JVM to the latest java 6 or
the latest java 5 from SUN. Make sure you have the last version.
Second: what is you current JVM and your current OS?
Third: maybe incrementing the Xmx is what create this specific error.
The JVM ask memory to the OS that is not able to satisfy the VM
requirements. You should better reduce the Xmx and if you start getting
*different* OOM from the JVM then you should analyze the heap content.
