[SUMMARY] Cannot use ulimit/unlimit to enable core dumps (coredumpsize)
2007-12-24 21:39:00
Rebooted the machine, NOW I can get unlimited coredumpsize!
On one particular system I could not enable core dumps. I
tried sh/csh/tcsh shells with the respective ulimit/unlimit commands,
nothing worked:
ulimit -c coredumpsize
unlimit coredumpsize unlimited
I never did get the coredumpsize to change from 0.
Albert and Arlynn reminded me that 'coreadm' manages core dump configuration,
see config file /etc/coreadm.conf. This was configured correctly,
with the same params as all my other systems where core dumps were
working fine.
