Hi,
I just ran into this yesterday on CentOS 6 / OpenLdap 2.4.36, my own build against bdb 5.1.29 and OpenSSL.
Dec 2 16:55:40 animal slapd[13735]: bdb(dc=clarku,dc=edu): /var/lib/ldap/log.0000032796: log file unreadable: Too many open files Dec 2 16:55:40 animal slapd[13735]: bdb(dc=clarku,dc=edu): PANIC: Too many open files Dec 2 16:55:40 animal slapd[13735]: bdb(dc=clarku,dc=edu): PANIC: fatal region error detected; run recovery Dec 2 16:55:40 animal slapd[13735]: bdb(dc=clarku,dc=edu): PANIC: fatal region error detected; run recovery Dec 2 16:55:40 animal slapd[13735]: null_callback : error code 0x50
I never did anything to change the default process limit, looks like it's set to 1024 in /proc/$(pidof slapd)/limits.
Is there anything I can do short of an automatic restart to prevent that from cropping up again? I have an MMR via Syncrepl setup with nothing too complicated; can't think of any reason offhand that slapd would need to have more than 1024 files open.
Best,
Aaron
