I have that error some up every once in a while. It sometimes seems to be accompanied by a perm gen out of space error. I’ve suspected that it might be related to the fact that we use trusted cache which gets cleared several times a day by automated hotfix migrations which slowly stack up the amount of Java classes. Either way, it’s an odd error deep in the bowels of Java and I never found anything when googling for it. How long had your server been online when it started? Does it only happen after several days?
Turning on some logging for Java memory might be useful to help troubleshoot. Railo shows it to you right in the admin, and tools like SeeFusion will display it for ACF, but unless Fusion-reactor shows perm gen, I’ve only been able to monitor it by enabling verbose GC.
Thanks!
