my slapd server is still crashing. I recompiled the slapd server already

what this random crash in the startup phase is causing.

Whenever you get a coredump, the most useful thing to do is to actually examine the coredump. Use a debugger to get a stack trace from the core file.

Okay i don't really know how to process core files. When I'm doing a pstack on the core file I'm getting this output.

-bash-3.00# pstack core
core 'core' of 5861:    /usr/local/libexec/slapd -d 511 -u 500 -g 500
  0008e1fc slap_sl_malloc (18, 185, ff092a00, ff3f4910, fe2c3040,
ff3f6a08) + 14

Looks like you ran out of memory to me.
