showing core dump error after connection of dual monitor

Hello All,

 

Issue is after connecting two monitors in HPUX C8000 workstations display is coming in two monitors.

But problem is wherever two monitors are connected for one application (MOCKUP Dvise) its showing some core dumped error at the time of loading even small parts also.

 

But for other workstations its working fine like large parts here users can load.

 

This tool is required for aircraft designing which support huge graphics .

 

So is it happening due to dual monitor and what's the solution for that?

What signal are you getting?  Any error message before it aborts?

Install gdb and get a stacktrace with "bt".

This error its showing before core dumped.

Pid 4218 received a SIGSEGV for stack growth failure.
Possible causes: insufficient memory or swap space,
Or stack size exceeded maxssiz.
Vcvisual terminated due to Segmentation Violation (SIGSEGV) , core dumped

So either you are out of swap:  swapinfo -tam   # do it before you abort

Or the kernel parm maxssiz is too small.  What is the current value?

kmtune -q maxssiz -q maxssiz_64bit

 

What does this show:  file core

 

Or you have a programming error in your application.  Using gdb's bt will tell you if you have a recursive stack overflow.

Error is not associated with application.

It seems core dump error is happening for monitor that’s connected with ATI FireGL X3 connector 2 in all workstations.

Seems to be enough free unless there was a big load difference.
 
>maxssiz 0x17f00000

At 400 Mb, this is probably too large.  So it isn't because maxssiz is too small.

Ok, in the executable Vcvisual.

>It seems core dump error is happening for monitor ...

Were you able to use gdb to get a stacktrace?
