It looks to me like the debug stopped too soon. The last line posted was:
.May 14 13:31:59.197: TPLUS: Received authen response status GET_USER (7)
which appears to indicate that the router has communicated with the server and has been requested to get the userID. This is part of normal processing.
I realize that the debug started with an indication of a timeout and that there may be a problem. But we do not see the context or the processing of the transaction that timed out. The amount and particular part of the debug posted is not enough to help us see the problem. Perhaps a posting with more of the debug would be helpful.
