Memory leaks, lag and server reboots

Shortly after the servers on Tranquility were patched last Wednesday we discovered a memory leak on them. 'Discovering' might be an understatement as the nodes actually gobbled up all the memory in few hours and then blew up in our faces. We have been working hard on identifying the cause for this and believe we have fixed the problem. Tranquility has been hotfixed but needs a proper update, so some stability issues remain. My apologies, I hope the situation will get better as soon as possible.
