Dear Gurus

My application vendor having problem while compiling some program using cobol compiler. They having error as below
"114 Attempt to access item beyond of memory - (signal 11)"

i have found below documentation saying low paging space could be the problem but after i increase paging from 1GB to 2GB,same error still persist.

http://docs.hp.com/en/64/hppg/hptrou.htm

your system is running low on swap space or you have exceeded the maximum data size allowed for a process, you may see the following error messages. In each case you may have to configure your system with more swap space or increase the value of kernel parameter maxdsiz.
105 Memory allocation error

114 Attempt to access item beyond bound of memory

198 Load Failure

200 Run-Time System internal logic error
My cobol server running in AIX 5.3 with 3GB memory and 2GB paging space and i have around 1.9GB free memory. Is this Cobol program error or Operating system problem? can anyone solve this puzzle???

Do i need to tune kernal parameter ?

Have you checked "ulimit -a" for the ID that they used to compile? You could try setting some of the parms to -1 and see if that works but you probably don't want to leave them as -1.

first get some clarity in here: when is the error message issued? during compiling or (more likely) during running the (succesfully compiled) cobol program?

the signal 11 is a unix signal sent to your process because a "Segmentation violation" has been detected, meaning it has tried to access memory somewhere where it is not allowed to.

this error 114 seems to be an error number from the cobol runtime code in reaction to the signal being received, and the textual description fits this picture.

Exhaustion of system ressources like memory or paging space most certainly looks different.

Now what? Get the application vendor to debug their code. Has it ever been running on aix before? Has a core file of the aborting process been written? look into the directory the process was running from. This would show the sw vendor where the program crashed.

Thanks for the feedback.Below is the my ulimit output and the vendor able to compile other Cobol problem without any errors but above error appear when they compiling this particular program. I not denied its could be error in their code . I like to know how to track memory leak in AIX (5.3) ? is there any command for it? Thanks in advance guys.
