Subject Cocoon hang in excalibur-pool
Date Fri, 16 Dec 2005 00:54:48 GMT
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
