On-Bar & ISM

I have successfully set up On-Bar & ISM on my brand new test server. I am now experiencing problems migrating my development server from On-Archive to On-Bar; As far as I can see both machines are configured the same. I was previously getting the following error in the bar_act.log XBSA Error: (BSACreateObject): A system error occured. Aborting XBSA session and in xbsa.messages _nwbsa_is_retryable_error: received a network error (Severity 5 Number 13): `hps03.hmgcc' is not a registered client. This was resolved by my Unix Administrastor defining hps03.hmgcc as an alias in Legato running on another server. Now When I run onbar -b I get NetWorker: RPC error, Unable to send NetWorker: Send Chunk to MMD failed, Broken pipe online.log shows that the archive has aborted on some dbspaces Level 0 Archive started on projectdbs Archive on projectdbs ABORTED bar_act.log shows Process 27396 received signal 13. Process will exit after cleanup. The On-Bar process 27396 exited with a problem (exit code 141(0x8d), signal 0). xbsa.messages shows _nwbsa_close_create_object_session: BSA_RC_ABORT_SYSTEM_ERROR System detected error due to savefile_fini() failure. Operation aborted. Some dbspaces and blobspaces are backed up and some are not. Can anyone help me ?
