Public bug reported:
While trying to reproduce Ubuntu Bug #921489 on a more modern release
(Natty) I seem to have triggered an assertion in slap_listener.
The test I am using is four threads of
while true; do ldapsearch -Y GSSAPI -H ldap://ldap.example.com uid=user
> /dev/null ; if [ $? -ne 0 ]; then sleep 2; fi ; done
within three minutes the server fails printing the following message
slapd: /build/buildd/openldap-2.4.23/servers/slapd/daemon.c:1846:
slap_listener: Assertion `((slap_daemon.sd_index[(sfd)]) == -1)' failed.
gdb output:
Core was generated by `/usr/sbin/slapd -d 0 -h ldap:/// ldaps:/// -f /local/sukat/conf/slapd.conf'.
Program terminated with signal 6, Aborted.
