core dump name of pthreaded program
|
|
| Tadek Dragowski 2006-02-13, 2:52 am |
| Hello,
When pthreaded program crashes it produces a core dump (providing core
dumps are enabled via ulimit -c) with pid extension no matter what is
the setting of /proc/sys/kernel/core_uses_pid. Non-pthreaded program
core dump extension correctly omits/appends pid based on core_uses_pid
value.
If crashing pthreaded program is automatically respawned it could chew
up disk space very quickly, since pthreaded core dumps are huge (in my
case 250Mb each). So I would like to keep only one core dump per
program.
I am using Linux pthread library (kernel 2.6.9)
My question is there another way to suppress appending pid to core dump
file name in pthreaded program.
Regards

Sounds like you should report this as a bug.

As a workaround, have your respawning remove the core file.

| As a work around I added a script run by crontab, which keeps only one
copy of the core dump, which allows be to debug original problem.
Actually your idea of cleaning up after respawning is even better - I
will keep the latest core-dump for the program and delete older one.
Thank you for your input.
