dumps on smb_panic regardless of platform since it skips exit_server
(I'm still confused on when exactly exit_server _is_ called 
if smb_panic does the abort() itself, but that's probably just me). 
I still haven't figured out where exactly someone tells the system 
'don't core dump on me', I'm guessing it's just done using a setrlimit
for the core size to 0 somewhere, but I still haven't found it.

<P><FONT SIZE=3D2>Maybe the core dump is done by the OS by default when =
the SIGSEGV signal is not handled by the process. Because Samba handles =
the signal to do the panic action, the system doesn't fall into the =
core dumping routine. Perhaps if, at the end of the exit routine, Samba =
dropped the handler for the SIGSEGV signal handler, and re-sent the =
same signal to itself, the core file would be dumped after the =
exit.</FONT></P>

<P><FONT SIZE=3D2>To set the core file size, use &quot;ulimit -c =
size&quot;. Read it with &quot;ulimit -c&quot;. Setting it to zero =
prevents core dumps. Note that I don't get core dumps from Samba, but I =
do from other programs, so this is probably not the issue.</FONT></P>
