Date Tue, 11 Jul 2006 14:54:03 GMT
Hi David, Martin, and Alireza,

Thank you very much for your comments and suggestions. Thanks a lot.

Hi David,
There is no logs corresponding to this shutdown anywhere on the system. I
couldn't find any thing relevent to this crash on syslog or at any other
place. Thanks for your help.

Hi Martin,
Here is the log from catalina.out file. Please have a look at it.

and here are the logs from localhost_admin_log.2006-07-10.txt

I couldn't understand much. Can you please let me know some more info about
this.

As you said, I tried to find some timeout parameters in the conf files.

<!-- Define a non-SSL Coyote HTTP/1.1 Connector on port 9080 -->
<Connector className="org.apache.coyote.tomcat4.CoyoteConnector"
           port="9080" minProcessors="5" maxProcessors="75"
           enableLookups="true" redirectPort="9443"
           acceptCount="100" debug="0" connectionTimeout="20000"
           useURIValidationHack="false" disableUploadTimeout="true" />
<!-- Note : To disable connection timeouts, set connectionTimeout value
 to -1 -->


In the server.xml the ConnectionTimeout is set to 20000. I will change that
to 0 and let you know the results. Thanks for your help.

Hi Alireza,

The tomcat I am using is not configured with apache.

Initially I run some sample application and left it ideal for some 3 to 4
hr. There is no action done in this time. Then the tomcat gets shutdown
unexpectedly.

I will try your suggestion and let you know the result. Thanks for your
help.

Thanks again for all,

Thanks and Regards,

Arunan
