Cocoon 2.1.7 hang

Thu, 15 Dec 2005 16:15:15 -0800

We tried to deploy an update to our product. Pretty much the only thing we did to Cocoon was to replace Xalan with XSLTC which produces a dramatic performance improvement. However, Cocoon is not consistently hanging. I tried to attach the thread dumps but they are too big. They also don't make any sense to me. I've reduced them down and pasted them below. It shows many calls to XMLFileModule waiting for a lock. The thread that has the lock is waiting for ResourceLimitingPool to get a lock. However, the thread dump doesn't show any threads holding that lock. Does anyone have any ideas on this? This is cocoon 2.1.7-dev svn revision 122686. Cocoon-2.1.7 is using excalibur-1.2. I can't find the source at excalibur. Anyone know where I can get it? 

Lots of theese waiting
