Are you talking about this one?
don't think tomcat by default ships with commons collections
But of course its not just commons collections its a more generic problem
that could be hit if there are more special classes that do special things
in deserialization.
i do think that tomcat by default (even the manager app or there jm

A quick Google search for "FATAL Database is starting up" seems to
suggest that is an error message coming from PostgreSQL and not from
Tomcat itself.
Hope that helps.

One correction, option -XX:-HeapDumpOnOutOfMemoryError disables heapdumps on
OOM, you should use -XX:+HeapDumpOnOutOfMemoryError - with plus sign, to enable
it.

As I said above, there is an options for JVM:
-XX:-HeapDumpOnOutOfMemoryError - it will make heapdump on OOM.
-XX:HeapDumpPath=./java_pid.hprof - give it an reasonable path to file.

Mostly leaner - a 32-bit JVM uses 32-bit pointers, so object references consume
less heap and stack space. Whether or not the code runs faster or slower
depends on what you're doing, since the tradeoff is fewer registers available
in 32-bit mode, which can lead to more register spills and re

You can look for biggest objects in heap (using MAT, Leak Suspects report,
Dominators Tree report).
This way you can try to find what was the exact reason of OOM instead of just
thinking "eh, I need to give instances more memory".
MAT does things good. I've already found using MAT+JVVM the rea
