"You have been automatically logged out for security reasons" on a clustered environment

I analyzed one issue today.

Some application exists on an BPM's environment. It executes some long process (the syncronization of LDAP's groups in my case).

This process takes about 5 minutes. But after 60 seconds the coach of this application is being changed to teamworks' coach with the message "You have been automatically logged out for security reasons etc..."

The message "The repository contact failed" on an offline Process Server

An offline Process Server can write this error in its log:


[7/4/13 11:27:03:297 MSK] 0000001d wle_servlet   W   CWLLG0095W: The repository contact failed with a status of: 500

It means that the Process Server attempts to connect to Process Center but last is not available.
