Databases and session management fall outside my expertise, but these do seem like possible causes.I know having someone looking over you shoulder asking you having tried this or that can be annoying as hell so sorry about that or if someone is already aware of this.
I found a post about what seems to be the exact same issue on another forum.
I don't know if the Lounge is running on the same stack as that forum but at first glance it looks pretty similar.
Digging a little further on that post a fix might be clearing / increasing the size of the in memory table holding sessions data. Granted the cronjob clearing that table doesn't hang.
As an alternative moving that table from memory to MySQL (if available) also seems to fix the issue.
