TCP Offloading

Symptoms

  • An exception is thrown in RavenDB Client when accessing RavenDB Server, because of a socket timeout
  • A general slow operation of client system

Cause

It appears that the machine hosting the RavenDB Server had the TCP offload functionality enabled, which seems to be causing connection drops, a problem experienced also by other applications like SQL Server.

Resolution

Disable TCP Offloading.
