>>Does your testing framework notice that Tomcat has been restarted?
yes our framework sees that Tomcat is not stable and i will restart tomcat.

Below are the logs from our framework, where it check for status of tomcat at
regular intervals and if the service is not consistent it will restart.
27-08-2012 18:24:52  119-70    information  "TSP:atcacscfn16.RtpSnm01:
RtpTomcatCheck -p 99 exits with ExitCode = 102"
27-08-2012 18:24:52  119-49    warning      "TSP:atcacscfn16.RtpSnm01:
Subsystem TOMCAT (Id=7) detector failed - ExitCode = 102"
27-08-2012 18:24:52  119-8     minor        "TSP:atcacscfn16.RtpSnm01: Restart

27-08-2012 18:25:39  119-6     clear        "TSP:atcacscfn16.RtpSnm01:
Subsystem TOMCAT successfully stopped"
27-08-2012 18:25:45  119-3     clear        "TSP:atcacscfn16.RtpSnm01:
Subsystem TOMCAT successfully started"

more information about the testcase.
Codenomicon is a well known Commercial robustness testing tool available for
various protocols. While running Codenomicom Diameter Server suite (which sends
both valid and invalid malicious Diameter messages to test the robustness of
the Diameter interface), the tomcat subsystem which hosts Platforms TSP GUI
goes for restart. During this time TSP GUI access fails. During a long run of
the codenomicon suite it is observed that the tomcat process restarts.

The testcase or the test case group where the issue is noticed is as below:
