Thread: Out Of memory Exception

1. The dump says this is an illegal memory access, not an out of
memory error. Where did you get "out of memory exception"?
2. Although the driver, is involved, this does not look like an error
in the driver. Is there something that makes you think that it is? If
anything, this looks like a native code error (JRockit itself?) if
this is indeed a memory access violation.

The PostgreSQL JDBC driver is written in pure Java, as far as I
know. So it cannot be guilty for a memory access violation or JVM
crash - it's either the JVM itself (albeit not probable at all)
or some native libraries in use..

Hi,

JVM's should not crash. I think you should address this with Oracle.
