Help Needed! Page reloads randomly when accessed thru BigIP URL

Hi Friends

 

I have a situation. When I am try to click any links or buttons when accessing it thru Big IP, the page reloads. This is sproadic and in past few days the number of reloads have increased considerably.

 

But the same when i try to access thru individual server URL everything works fine. I am not able to suspect something wrong with the code as the application still works fine. Any help pls..

    Hi Arun,

     

     

    I'd suggest using a browser addon to capture the HTTP requests and responses on the client like HttpFox for Firefox or Fiddler for IE. This will allow you to compare a failure and a success. If it looks like it's an issue specific to LTM, you could capture a tcpdump on both legs through LTM using a tcpdump command like:

     

     

    tcpdump -ni 0.0 -s0 -w/var/tmp/trace.1.dmp host CLIENT_IP or host SERVER_IP_1 or host SERVER_IP_2

     

     

    where CLIENT_IP is the client IP address and each pool member IP is listed after.

     

     

    If you need help capturing or analyzing the tcpdump, you can check AskF5 SOL411 or open a case with F5 Support.
