JVM crashes

[Alfredo_32]

we got a core file when the JVM crashes. Our weblogic version 9.2 and the code consist of a simple servlet. I think, it is an error in the weblogic socket muxer.
I attach you the hs_err_pidxxx.log content.

Shalom,

1) Needed OS java patches not installed.
2) Bad application code.

SEP

My lab colleague says after following SEP's advice, you need to contact the Response Center or BEA support.

Hello,

I get similar errors in my application which is currently running on WL8.1, but in this case seems to be related to memory handling:

# An unexpected error has been detected by HotSpot Virtual Machine:

any advice on this ? could it be OS patching issue or JMV bug probably ?

thanks!

>any advice on this? could it be OS patching issue or JMV bug probably?

Same as before, make sure you have the latest Java and HP-UX patches. If you still have a problem contact the Response Center.

Though this one seems to be a GC error.
