2009-01-22 06:54:33 Thread-4105165728 ERROR fetchlets.oslinetok: Metric execution timed out in 600 seconds
2009-01-22 06:54:33 Thread-4105165728 ERROR command: failed to kill process 4793 running perl: (errno=3: No such process)

Cause
The Response metric is making a timed out then the Agent starts other process to take the Response metric. The process to kill the PID taking the Response metric is failing increasing the process running dbresp.pl

Before the Response metric starts to do the timed out  there is other error:
