Applies to

  • SnapCenter Server
  • No firewalls between SnapCenter server and plug-in hosts

Issue

  • SnapCenter backup jobs fail due to System.Net.Sockets.SocketException randomly occurring on the SnapCenter server host side or plug-in host.
  • The error appears in SnapManagerWeb_<JOBID>.log on SnapCenter server or SMCore_<JOBID>.log on a plug-in host.

Example:

ERROR SMCore_309 PID=[9244] TID=[36] PostRequestAsync exception : System.Net.Http.HttpRequestException: An error occurred while sending the request.
---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.
---> System.Net.Sockets.SocketException (10054): An existing connection was forcibly closed by the remote host.

  • No errors in the job logs and Windows event logs on the remote host side.
  • The phase or operation in a backup job where the error occurs is random and inconsistent.
  • Depending on the phase where the error occurs, the job status keeps running and never completes.
  • Sometimes, the job keeps running without any explicit error in SnapManagerWeb_<JOBID>.log on SnapCenter server or SMCore_<JOBID>.log on a plug-in host.
  • Packet traces captured both on the SnapCenter server side and the plug-in host side show many TCP retransmissions and lost packets.
