We have experienced random slapd segmentation faults, when the relay backend and rwm overlay were used in the configuration. After some time I could reproduce the segmentation fault on a slow client and with test queries, which were supposed to return a larger set of entries.

I could trace the problem to a wrong pointer in the slap_writewait_play function in the openldap-2.4.44/servers/slapd/result.c file, and then further to the openldap-2.4.44/servers/slapd/back-relay/op.c file. After the addition of the sc_writewait pointer initialisation (see the patch below), the test queries returned correct results and random slapd segmentation faults disappeared.

Thanks for the report, but this was already fixed in ITS#8218 released in 2.4.43. Sounds like Red Hat has botched their source code since the official fix has been out for nearly 2 years already.

Sorry, a typo on my part. It was ITS#8428.
