Resin 3.0.28 and strange memory issues.

    Hello everyone,
    We've recently upgraded some of our production apps to Resin 3.0.28
    (from 3.0.23), and some of them (only some) have started acting very
    strangely. We were getting random OutOfMemoryExceptions, on the heap.
    We increased the heap, thinking Resin just needed more memory, but then
    we started getting OOM "Requested array size exceeds VM limit".

    Our application code hasn't changed, and when we attach an agent to try
    to find the problem, it goes away :-(.

    Any suggestions? Anyone with similar experience with Resin?

    Thanks,
    Daniel.

    First:
    -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/path/to/directory

    It being fixed by a debugger makes me think that you should try a
    different version of the JVM or try removing old and obscure options
    that may not work correctly anymore. Most people never see JVM bugs but
    they're definitely there and large applications show them more.
