Terminal IBM3270 Timeout 10min10 sec

I am facing the same problem as in topic Terminal IBM3270 Timeout crash

Randomly the process stops for 610 seconds (plus/minus a few seconds). Once the time has passed the process continues as if nothing has happend.

I didn’t see any solution in the responses but they were a bit old. Has anyone found a working solution? It seams to be a fixed timeout-time , is it possible to change this?
