hello all,

I upgraded to OpenLDAP 2.4.43 three weeks ago. It runs on debian
squeeze 64bits lts
it is built from sources with the fix from ITS#8330

Since the upgrade, it keeps crashing regularly (I would say once
every 2 to 5 days)
However, there isn't anything in the logs: no message, no error, no

slapd no longer runs, I restart it, and it runs ok until the next

now I don't know how to debug that.
What are your advice to track down the cause for the crash?
Check whether openldap has been built with --enable-debug=yes.
If so set ulimit -c unlimited, which hopefully will create a core dump
on a crash.


very interesting. Yes it is compiled with enable-debug
I have just enabled core dumps

according to the internet (tm) [grin], this is how I get a stracktrace, right?

    gdb --core /path/to/THECOREDUMP <<<"thread apply all bt full"
it seems that this command is better:

gdb /usr/sbin/slapd -c /path/to/core <<<"thread apply all bt full"

to associate the core with the program that generated it
can someone experienced confirm this?

also, in your experience, in case of a crash, can the debugging packages (i.e. slapd-dbg and libldap-dbg on debian) be installed a posteriori to enable better traceback informations?

thanks again for any help. regards,
Jephté CLAIN

thanks! regards,
