Hi Cosio
thank you very much.
There is no such suspecious servlet details in web.xml
Hi All,
My problem seems to be very peculiar and haven't heard this before.
The tomcat gets shutdown unexpectedly after 3 hours only on this particular
system.
the same tomcat with same confgiurations when run on a other system, it runs
properly and there is no problem.
on this particular system the problem occurs always.
# uname -a
SunOS CBT 5.8 Generic_117350-36 sun4u sparc SUNW,Sun-Blade-1000
dunno what to do. i have tried all.. nothing is fruitfull.
Also it is very amazing that when i run a simple script at background which
will echo hello once in 10 minute and is infite...the problem doesn't
occurs...dunno why...
while [ true ]
do
echo "hello"
sleep 600
done
why?
whats the problem?
How to resolve?
I am very much confused.
Please help.
Thanks again,
Thanks and regards,
Arunan

David,
- Do you have in your web.xml some kind of <servlet> tag sometimes used
to start a background thread that might be causing the problem?
Unfortunately I work with WinXP and not everithing is written to
catalina.out, what I do is run tomcat in a DOS prompt, if it hangs then
I can read all the output generated, sometimes caused by the JVM...
- Are you trying to open de /admin tool but it's not installed already
on your server?

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
