Hi,
Even after making the timeout parameter to 0, still the problem exist.
Even I ran a continous polling application in the tomcat and still the
problem exist.
The tomcat server gets shutdown unexpectedly after some irregular period of
time 3 or 4 or 6 hrs. However this problem doesn't exists in other sun
machines.
Only in a particular system it is occuring. Please help me out to find whats
the problem with the system and the tomcat server.
Machine Detail: SUN OS 5.8
Tomcat versio: 4.1
Please help.
Thanks again.

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.

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
