Guys, we had massive java crashes over the course of the day and I have no idea what is happening. I first rebooted the machine, undid some changes in the hope it would fix something, and it worked for 2 hours or so and then crashed again several times. I have upgraded a couple of things but I cannot trace the issue. I got a [Too many errors] on the console as well as the crash report from java at times:

with different contents in “Problematic frame”. This is quite a serious issue that is why I have created a new, temp bukkit server and will now see how I can add plugins one by one and see if it works. So until then the normal server will be frozen. Unfortunately this comes at the worst of times since I will be leaving for a trip tonight for 2 weeks. I will see how much I can fix during the trip, but it looks like we will have to live with a not-fully operational server for some days. If you have any ideas how to debug something like this, please let me know. All help greatly appreciated.
