We have an error that occasionally takes down our website where we have to reset the application pool to revive it. It looks to me like this error comes from CuteChat because it is the only thing in the application pool utilizing session state plus the error comes from a timer which is another hint that it is CuteChat. Please see the two error logs below and let me know your suggestions:
