RE: slapd stopping with no error message

I apologize, but I am not familiar with gdb. I attached to the process,
it crashed with a seg fault. What should I be typing in now? Thanks!

Thanks. I am compiling with efence library right now. I am not too
worried about the speed, it is not prod. I would like to run it under
gdb, and I will try that, the problem is that if I loose my connection
the only thing I can think of is to kill the other gdb, then re-attach.
I guess that would not cause a problem. I was hoping with the cd and
ulimit that the core would be generated and then gdb on that. Thanks!

Still better to run under gdb. But given the fact that you're getting 
heap corruption, you're really going to need something like efence in 
addition. Unfortunately that's going to make things run very slowly, but 
that's the only sure way to identify the root cause of the problem.
