jsp written by a customer crashes a few times per day.
It is application which works with
- BEA Weblogic 5.1 sp12 wlcs 3.2sp2
- HotSpot Client VM 1.3.1_04-b02 (and 1.3.1_03-b03)
- Ultra Enterprise 450 5.7 (and 5.8)

Application makes some large table in the memory
This problem is only on multi CPU machines.
Customer checked his application on few machines and Solaris verions.
It looks like it does not depend on architecture (Sparc II/ Sparc III) nor Solaris version (7 nor 8).
It worked fine on one cpu server.

Location of core files and explorer output for solaris 7,8:

They are too big to be attched to bug:

Using the sol8 core I see they have tested -server too:

Checked patches for sol8; see also complete report in attachment webpatchdiag-sol8.html
