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

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.

gliese581_330353ks,It's not a httpd error of LTM,it's a secure log located in /var/log
how can I capture a tcpdump?
