I am using Debian 6, GlassFish Server Open Source Edition 3.1.2 and Java 1.6.0_26-b03.

Hi Sharinga,
It looks like you are missing the terracotta toolkit jar (i.e. terracotta-toolkit-1.5-runtime-4.2.0.jar) from your classpath based on the NoClassDefFoundError below.

I'm not sure what the toolkit-runtime jar would have to do with that exception. The class referenced (net/sf/ehcache/concurrent/ConcurrencyUtil ) is part of ehcache-core.

I don't have an explanation for that really. Does this happening at any particular time? Specifically was the server shutting down or your web context being stopped and/or re-deployed?

If you can give us something to repro the issue we could likely get a lot further
