openldap under openbsd

I was curious if anybody is running openldap under openbsd? The version in their ports system has mdb disabled, it says mdb is unreliable and results in random slapd crashes. It seems openbsd lacks a unified buffer cache, so mdb can only be used with the MDB_WRITEMAP option; they added a patch to cause initialization to fail if that option isn't enabled but then ended up disabling it completely anyway. This was back in 2015, I'm not sure if they've tested it recently or what details there were behind the crashes before they ended up disabling it.

I'm thinking of trying it out with the latest release and seeing what happens but was wondering if anybody else had any recent experience.

Thanks...
