Hi Maxim, I read the ticket. It's not exactly the same problem. In my case, users do not login from the OM's login window, but the API is used with a generic user with SOAP rights. Also, the problem is not a constant, which makes harder to reproduce. I have goten the error randomly. I'll try to do a test program to list rooms hashes in loop and concurently, to see if I can find something.
