Hi All,

Please find below the description of memory leaks issues.

1. Statistics show major growth in the perm area (static classes).
Flows were ran for 8 hours , Heap dump was taken after 2 hours and at
the end. A growth in Perm area was identified


So what's loading classes and not collecting them?

2. Statistics show from our last run 240MB growth in 6 hour,40mb
growth every hour 2GB heap ???can hold ?? days ,heap will be full in ??
days
Heap dump show ???growth in area as mentioned below

....

we are using
Oracle BEA Weblogic 9.2 MP3
JDK 1.5.12
Oracle versoin 10.2.0.4 (for oracle we found one path which is needed
to applied to avoid XA transaction memory leaks).
But we are stuck to resolve SUN, BEA Weblgogic and Apache leaks.


What makes you think those well-established products are responsible for the
leaks and not the application code?

Does that obsolete version of Java support perm-gen sweeping for GC?
