Start slapd on the server that's crashing
Get the process ID of slapd
gdb /path/to/slapd PID
For example, if slapd is located in /usr/sbin, and the process ID is 1234:
gdb /usr/sbin/slapd 1234
At the (gdb) prompt, enter the command "cont" to continue execution
Run your operation that causes slapd to crash. This should drop you back
to the (gdb) prompt.
Then run the command:
thr apply all bt full
This will provide the full backtrace.
