Re: [MLUG] RH - how to enable coredumps?

[Mark Haidekker <EMAIL:PROTECTED>]

Melissa and Mike:

thanks for your suggestions. However, they do not apply. limit / unlimit is 
SGI, no? I don't have those commands on my system. Also, limit coredumpsize 0 
_does_ create a core file, albeit with zero length. In my case, there is _no_ 
such file.

As for limits.conf, there simply are no limits:
[EMAIL:PROTECTED] ulimit
unlimited

[EMAIL:PROTECTED] quota
Disk quotas for user myself (uid 500): none

bashrc and /etc/profile give no indication of limiting something...

Any other ideas?

Thanks,
Mark
