Hi Zhang,

We are frequently facing temporary failure issue and meanwhile mailq is getting increase to huge amount. Find the below maillog error.

Oct  3 12:18:49 xyz postfix/pipe[23079]: 32BCC157EE5: to=<abc@mydomain>, relay=dovecot, delay=49, delays=7.9/3.6/0/38, dsn=4.3.0, status=deferred (temporary failure)

After we try to restart the ldap service and we are getting following error.

Checking configuration files for slapd:  bdb_db_open: unclean shutdown detected; attempting recovery.
bdb_db_open: Recovery skipped in read-only mode. Run manual recovery if errors are encountered.
config file testing succeeded

Kindly treat this on high priority, and let me know if you need any other information.

Regards,
Pinemail
