Apache - Weblogic Connection Issue

Question

Hi
we are facing with Apache weblogic communication issues.
The communication with Apache and Weblogic works for some time ( few hrs), But after some time we get the below error.
Let us take one pair. (Apachedevv1 ----> Weblogicdevp1)
Yesterday evening it was working fine. Today morning I see the below error.
http://Apachedevv1/
Failure of server APACHE bridge:
No backend server available for connection: timed out after 10 seconds or idempotent set to OFF.
Build date/time: Apr 20 2009 21:26:02
Change Number: 1211636
Then I run the below command on Weblogicdevp1
C:\> telnet Apachedevv1 80
This is success as the Apache is running on Apachedevv1:80
Now If I access the URL http://Apachedevv1/ it is success now and I get the weblogic home page.
Pls let us know if you had face this type of issue earlier.
Following are the lines added in httpd.conf of Apache.
<IfModule mod_weblogic.c>
WebLogicHost Weblogicdevp1
WebLogicPort 7001
</IfModule>
<Location />
SetHandler weblogic-handler
</Location>
I see the below errors in error.log of Apache.
[Wed Dec 29 09:10:59 2010] [error] [client xx.yy.49.39] ap_proxy: trying GET / at backend host 'xx.yy.86.54/7001; got exception 'CONNECTION_REFUSED [os error=0, line 1715 of ../nsapi/URL.cpp]: Error connecting to host xx.yy.86.54:7001'

The error means , there is no application server running on that port configured in apache that is 7001 at the time of issue.
One more thing you are doing telnet on 80 , but you should do telnet on 7001 and not on apache port.
So if you face the issue again, please do telnet on weblogic host like " telnet weblogicdevp1 7001".
It's not problem with apache version and weblogic plugin version.
You can integrate weblogic with apache using mod_proxy module also, pls refer the below link for more info:
