I had researched the below errors for TSM client on a Novell system a while ago. If I recall, I couldn't find anything specific on the list server, other than it's a TCPIP problem. In my case is was a simple TCPIP problem. The NIC card was set to 10mbps/half duplex and the port on the switch was set to 10mpbs/full duplex. Once we changed the port to 10mbps/half, the errors went away and backup performed normally.
Just thought I'd pass it on. kyle 10/31/2001 12:27:09 TcpRead(): recv(): errno = 54 10/31/2001 12:27:09 sessRecvVerb: Error -50 from call to 'readRtn'. 10/31/2001 12:27:09 ANS1809E Session is lost; initializing session reopen procedure. 10/31/2001 12:27:09 ANS1809E Session is lost; initializing session reopen procedure. 10/31/2001 12:27:25 ANS1810E TSM session has been reestablished.
