Symptoms

The Management agent is crashing after few minutes running.

The emagent.nohup file shows:
...
10:51:20 2008::Checking status of EMAgent : 22027 -----
----- Mon May  5 10:51:20 2008::EMAgent exited at Mon May  5 10:51:20 2008 with signal 6 -----

But if the Database is down the Agent remains running without problems.
