Exchange 2013 transport service crashing

hi there,

We are migrating from 2010 to exchange 2013 (now sp1) but have a problem with the transport service crashing. The event log seems to indicate that its due to a tcp/ip socket error (see below).

Can anyone suggest how to troubleshoot this further?

Cheers,

Al
