Within the last couple of weeks, I've seen some transports seeming go to sleep. They do complete, but in a very long run time. One transport ran overnight for almost 12 hours to complete. I started monitoring, then as you can guess, they seem to run normal. Now this morning the problem has resurfaced, with one that has been running for about 6 hours.
Here is the program stack of the transport job. Notice the 'sleep' procedure that has been called. Does anyone know why or what makes this occur?
