I am trying to execute one application on HP-UX vvvvv B.11.11 U 9000/800 697359306 unlimited-user license. It is giving me core dump.It is a C++ Application .

Appreciate if you can please let me know your inputs. Thanks!!

Can you post what exactly the error message before
core dump? How big is your C++ file?

Hi,

You may try to increase kernel value of maxdsize.

Thanks

According to your truss output, the process received a SIGABRT which is usually due to someone pressing CTRL-C when the process is running.

[Rohit Goyal]

The size of my executable is :- test.out (9121416)

[Rohit Goyal]

I am not pressing ctrl+ c


My program is Aborting due to some reason which i am not able to figure out

$ ./test.out
Inside main()
Before DatabaseUtil::Instance
=== LOG BEGIN === 02/17/2005 16:31:04 NONDB_LOG(Level = ERR,0) use KTK_[NON]DB_LOG to change
Connecting to omordtst/omordtst as ddlbos6
Abort(coredump)

Your truss output show the following error

mmap(NULL, 962560, PROT_READ|PROT_EXEC, MAP_SHARED|MAP_SHLIB, 6, 0x45000) .............................. ERR#12 ENOMEM

This shows that a mmap call failed due to ENOMEM, which is because there is insufficient room in the address space to effect the mapping. (as you are not useing MAP_FIXED).

So you need to increase the memory in your address space.
