I was looking for something more general. Surely this time it was cause by NTP, but who know what will happen next.

Similarly linux running 3.1.10-1.9-default and 2.6.35.14-97.44.amzn1.x86_64 had issues while 3.1.6-gentoo did not. I suspect the problem with run-away java threads has been addressed in more recent versions of Java and is not related to the linux kernel version.
