Bug Description
In our installation slapd will crash with a Segmentation Fault about once a week. It has been seen on the producer while the consumers connect but also on both producer and consumers at random. It seems to be related to authentication with GSSAPI.
syslog produces the followig message:
kernel: [513493.152760] slapd[1610]: segfault at 7fb242df9000 ip 00007fb242ad7122 sp 00007fb127ffd900 error 4 in libcrypto.
gdb:
Core was generated by usr/sbin/slapd -d 0 -h ldap:/// ldaps:/// -f /local/

The backtrace is incomplete as the debug packages are broken. Trying to reproduce this bug I trigger another segfault. I will file reports on thease issues in
separate tickets.
