Re: Session handling problem
It would appear that the call to login is blocking. But we have only experienced this in our live environment which I don't have direct access to so I am relying on second hand information. Also for this reason getting a thread dump is more difficult. Leave this with me and I will try and put some more logging into the system. Also I will see if the services team can grab me a thread dump. Although I wonder if the limitation you have linked me with could be my problem. I will do some more investigation and update you once I have a bit more information. Thanks for taking the time to give me some more ideas, Shane.
