stack overflow.

ragesh_3 — Fri, 03 Apr 2009 11:18:07 GMT

Pid 23597 was killed due to failure in writing the signal context - possible stack overflow.
No successful completion message printed.

Getting this error when users running one application script .

Can anyone help me to find the cause of this error ?

Hi,

well, you can try to tune the kernel and to increase the maximum size of the stack of a process ->

You need to analyze the stack trace. It could either be a main stack overflow or a thread stack overflow. The former can be adjusted by Volkmar's maxssiz. Thread stacks require calling pthread_attr_setstacksize(3).

Of course your application could have a recursive stack overflow and no matter how big you adjust it, it will fail.

Also don't forget maxssiz_64bit in case this is a 64-bit process.
Check the syslog. All errors caused by kernel parameter overruns are logged therein - unless the overrun itself prevents writing the log. But then the system would have ground to a complete halt anyway.

My $0.02,

If you need a stack this large your application is broken or possibly Fortran. ;-)

Not for user problems.
