A network problem has been encountered.
2006/09/07 09:41:26.34 RepAgent (10) Error: 9210, Severity: EX_CMDFATAL, State: 1 Fatal error from CT-Lib.
Open Client Client-Library error: Error: 84083974, Severity: 5 -- ct_results(): unable to get layer message string: unable to get origin message string: Net-Library operation terminated due to disconnect.
You see these messages when there are network problems; for example, when a RepAgent cannot initialize a Client-Library connection, or an SAP Replication Server returned an unexpected error. Network problems can also cause RepAgent error 9212 (which is caused by a CT-Lib error).
Fix the network problems and restart RepAgent. After you fix the network problems, execute admin who_is_down on the SAP Replication Server. You see that the REP AGENT USER threads are down.
