After certain interval of time system hangs and stating the error "Agent not responding".
What is the solution ?
I haven't found a solution to this either. When this happens, i kill the agent process (sometimes it's necessary to restart silktest), and restart my test.
Life's a b***h and then you die.
This happens often when memory leaks in the tested application are existent.
If this happens I usually make purify analysis with rational purify.
When this problem is fixed the tests run without problems, mostly.
