HI,

Please look into this as an extremely urgent issue :-

We are facing some serious problem with our production environment, which is about to go live.

Our setup is;

Siebel 7.7.2 with QF 1007.

We use thin client only.
Around 20 + application server, out of which 8 have eCommunication Object Manager running on them.
3 Sunone web servers with SWSE plugin. CISCO load balancing switches between web & application servers & also between clients & web servers.

When we start the servers running eCommunication OMs, everything works fine for some time (1 or 2 hours).We can hit all 4 OM servers, can see user logged on each of them. But after some time we start getting server busy error as below.
“The server you are trying to access is either busy or experiencing difficulties. Please close the Web browser, open a new browser window, and try logging in again.[16:41:34]”

We can still connect with server manager from command line & see all components
including eCommunication OM running.

If we bounce eComm OM servers, then again it works for some time.
The eCommunication OM logs on all servers have connection time out messages.

The log files from siebel web server extension & application server attached.
