timeout problem

We have a f5 cluster to service for my web application.

 

recently we meet a question. some of my customer feeded back to us they can't login application using the f5 virtual servers,but no all user like this,part of them can use it.

 

I check my f5 log, I found the following information

the picture is that I captured it through a website monitoring tool that I used it to monitor my application website.

 

I want to ask if some of my error configuration may lead the problem

    Is that the httpd error log from LTM? If so, that's for the admin GUI and isn't related to the issue.

     

     

    I'd suggest trying to capture a tcpdump of a failure to see if the request is making it to the virtual server and if so where it's failing. Try searching this forum or the AskF5.com site for 'tcpdump' for details on using tcpdump.

    3ks,It's not a httpd error of LTM,it's a secure log located in /var/log

     

    how can I capture a tcpdump?
