Hello K reddy,
This is an old post but did you manage to understand what happened after the crash?
Our REP server just crashed with the same error but we could successfully restart it:
"Replication Server failed with fatal error while allocating memory. Most likely, there is not enough memory. Replication Server is going to abort."
Memory_limit=2048
6GB free of RAM (out of 8GB) before starting REP server.
Version:
Replication Server/15.7.1/EBF 21458 SP102 rs1571sp102/Sun_svr4/OS 5.8/1/OPT64/Mon Jul 15 18:06:33 2013
thx
Vincent
