    B4 - Server failed to flush BER data back to client

    bhadra12

      Hi All,

       

      Issue with the client of directory server (ODSEE 11.1.17 on RHEL6) during user authentication.

      Client is CISCO appliance

      Error in access logs : B4 - Server failed to flush BER data back to client

      Before the issue: Client had successful connection and some rare failed connections (I see above message when it fails after successful bind)

      When issue started: All the events are failed with above message after successful bind.

       

      Failed event is :

      I read below thread but the SAN in certificate is already set to loadbalancer FQDN and directory server's FQDN.

      Many other client connections are successful(all operations in connection) eventhough there is same error message.

      I wonder why one perticular clinet got impact?

       

      Thanks to look into this.
