I would appreciate if you could help. Currently we're experiencing problems in our website. The website is load balanced with cisco ACE module, Virtual IP has been NAT'ed outside and was working well till now. There are 2 web servers in serverfarm ( both are in DMZ). Ping is working ok to all these separate servers. (note that web servers are on AIX)
ACE is configured with Http probe, when i'm troubleshooting the problem from ACE, what i notice is that when connection number goes up, ACE stops receiving 200 ok message from both servers (sometimes one will fail, other will fail later). After http probe failure, Virtual IP becomes outofservice and at the result website becomes unavailable.
When one of our admins restart apache and tomcat in that server, http probe will go back to success state and Virtual IP will come back again. Failures happen periodically.
Could you please help me finding out why http connection fails with individual servers? How can I fix the problem? Is there anything to do with ACE configuration?
Thank you very much,
Appreciate your efforts.
