Is the server crashing, or is replication not working? There's a big difference between the two. If it's crashing please obtain a stack trace from the core file: https://www.port389.org/docs/389ds/FAQ/faq.html#sts=Debugging%C2%A0Crashes If it's just replication not working then we need a lot more information. Access logs, error logs with replication logging enabled, and the replication agreements. Look through your access log and track down what client is opening conn=36614. is this a replica or some other client? The Replication is not working? I mean there is the crash of Replications. Below list of error are shown in the access logs : [25/Oct/2022:02:03:15.698645866 +0200] - ERR - slapi_ldap_bind - Could not send bind request for id [cn=Directory Manager] authentication mechanism [SIMPLE]: error -1 (Can't contact LDAP server), system error -5987 (Invalid function argument.), network error 107 (Transport endpoint is not connected, host "myserver:389") [25/Oct/2022:02:06:27.558971677 +0200] - INFO - NSMMReplicationPlugin - bind_and_check_pwp - agmt="cn=lpfroot12" (wa2p:389): Replication bind with SIMPLE auth resumed [25/Oct/2022:07:25:15.490236609 +0200] - ERR - log_ber_too_big_error - conn=36614 fd=78 Incoming BER Element may be misformed.
