Thank you Vitor. It is very close, what you copied here. Today we were able to solve the problem...the problem was in the algo in the F5 load balancer...we configured it to sticky session, and now reports started working perfectly.

We did few steps, including restarting servers, viewing different log files, event views in different FE. We also try to log using fiddler or f12 tools...nothing worked, till we give this option a try. Usually, CRM handles F5 configuration in nice way, but SSRS reports wants sticky session. once we configured that way, it worked flawlessly.
