HotSpot Virtual Machine Error, Unexpected Signal 10

Hi Folks,

We get the following error, when running our application. We are running HP-UX 11.00 on a L-Class server, with WebLogic server 5.10 SP10 and Java 2 SDK 1.3.0.01

An irrecoverable stack overflow has occurred.
Full thread dump:

"HighPriority TimeEventGenerator" daemon prio=9 tid=0x8d270 nid=31 lwp_id=24297 waiting on monitor [0x6aee8000..0x6aee8438]

and the WebLogic server aborts in a core dump. Can anyone let us know what's going on.

Cheers

You probably need to increase the stack size with
a -ss option to increase the native stack size or
a -oss option to increase the java stack size,

Hi


Try using

-XX:CompilerThreadStackSize=xxxx

2048 is default so try 4096


java -XX:CompilerThreadStackSize=4096

I would check that all prerequisite patches from http://www.hp.com/go/java are installed and in a correct state.

I would also unless the application warns against it consider upgrading to the latest java release. Cut out some variables.

Also make sure PATH and SHLIB_PATH is correct for the user that starts and stops the app(and owns the binaries).

Re: HotSpot Virtual Machine Error, Unexpected Signal 10

You are using a pretty old version of Java 1.3. I would consider, upgrading, installing the required patches and increasing the stack.

The root cause is the stack issue, but my other comments are also valid.
