Weblogic Apache Bridge Error - Urgent

Question

Hi,
We have installed 11g weblogic and forms and reports successfully but while calling a form sometimes in concurrent sessions getting 'Failure of Server Apache Bridge Error'.
Following are the system details:
System: Windows 2008 64 bit
Forms/reports [64 Bit] Version 11.1.2.0.0
Weblogic server :10.3.5
Apache Version:
Oracle_FRHome1\ohs\bin>httpd -version
Server version: Oracle-HTTP-Server/2.2.15 (Win32)
Server built: Apr 2 2011 17:14:20
Server label: APACHE_11.1.1.5.0_WINDOWS.X64_110325.2000
As suggested in most of the forums, we have disabled IPv6 and replaced hostname with IP Address of the system in mod_wl_ohs.conf, forms.conf and reports_ohs.conf like this:
mod_wl_ohs:
DynamicServerList Off
WebLogicHost 10.11.18.119
<Location /console>
SetHandler weblogic-handler
WebLogicHost 10.11.18.119
WebLogicPort 7001
</Location>
WebLogicPort 7001
<Location /em>
SetHandler weblogic-handler
WebLogicHost 10.11.18.119
WebLogicPort 7001
</Location>
<Location /forms>
SetHandler weblogic-handler
WebLogicHost 10.11.18.119
WebLogicPort 9001
</Location>
<Location /reports>
SetHandler weblogic-handler
WebLogicHost 10.11.18.119
WebLogicPort 9002
</Location>
And from weblogic console also we have changed the listen address to this static IP and restarted the ohs,form, report server.
But still facing the same issue.
Any suggestion?
OHS Log:-

Any prompt help would be highly appreciated.
Thanks in Advance.

Answer 1

Thanks for the prompt reply.
We can access the report with 2 or 3 concurrent connections properly but the moment there are more concurrent connections it gives 'Failure of Server Apache Bridge Error' in client browser for new connections and whoever is already logged in their application gets hang.
So restarting also wont help as there can be more than 100 concurrent connections.
We have changed few parameters like :
StartServers 2
MaxClients 2500
MinSpareThreads 25
MaxSpareThreads 2500
ThreadsPerChild 25
MaxRequestsPerChild 0
KeepAliveTimeout 15
Timeout 720
Any other suggestions?
