Hi,

i tried google but not able to get anything useful

i m debugging  network/multithreaded program, but not able to get
anything from core file, because of   singal 9.

Program terminated with signal 9, Killed.

any way to debug this ?

followings are some detail about gdb output , gdb version and OS
version  ?
I think i faced signal 9 -core file first time. ? Is it ok to have core
with Signal 9 ?

( i am very much sure none has used kill -9 prog_name)

--Raxit

Which wont help if you use a stripped program.

Yes.

"Nobody", maybe, but when the OS runs out of virtual memory (ie, page
file is full), it will pick user processes to kill. There may be
traces of that in the system logfiles.

My Binaries are not-stripped,
also most of all 3rd party library are not-stripped (or i am able to
recompile and built again) (Except System libs, like libc,glibc etc...)

i am able to disassemble, but as i m not expert in this it is helpless
for me.

also i am able to view number of threads (in core files using gdb and
some information ) but not sure this information is consistent ?

any idea on this ?
