Hi list, I'm experiencing some problems with and LDAP box which used to run 2.4.21 and has been upgraded to 2.4.22
The box act as a pam_ldap/nsswitch login server for a bunch of boxes, let's say 20, and serve the mail server and web proxy server as a user base.
The box has 2G of RAM and has an average load very low, let's say top/systat shows 0.40.
The issue is that it happens from time to time every 2/4 days that the slapd daemon exits on signal 6:
May 12 01:00:00 polido kernel: pid 27153 (slapd), uid 389: exited on signal 6
Then i restart the process everything looks fine and no corruption seems to happen in the DB. The box is a FreeBSD 8
Any clue is really appreciated.
Thanks

Running in debug mode (-d 7) I got this output just before the crash.

As always any hint is really appreciated...
Cheers

This is bad. You should file an ITS, and send a stack backtrace, possibly looking at the content of the string that caused this parsing error. See instructions here http://www.openldap.org/faq/data/cache/56.html.

Make sure you have debugging symbols built in for slapd and everything it links to (sasl, etc), and then run it under GDB. Once it aborts, get a gdb backtrace. Alternatively, enable core files while having all those debugging symbols available so that you can get a gdb backtrace.
