I am using OFBiz 4.0. I been trying to figure out what causes random high CPU utilization from OFBiz since its deployment (08/2009), which usually requires a restart of the application. I have done lots research at the software and hardware level and tried many changes, including replacing Minerva with Apache DBCP, but I still (seemingly) random times when my server CPU is at 100% utilization, all from the OFBiz application.
I think I may have stumbled upon a possible reason. The most recent time it has happened I did a thread dump--something I wish I did last year. The thread dump showed one particular process that wasn't finishing, and seemed to be stuck on org.apache.commons.collections.map.AbstractHashedMap.put(AbstractHashedMap.java:273). The OFBiz log showed the same. A packing session was being completed and gets stuck on that put function. The thread stack is pasted below. I am wondering if this rings any bells with some of the more veteran developers. I found this URL (http://www.mail-archive.com/dev@ofbiz.apache.org/msg14324.html) which seems to be related to my issue. I also saw that on 4/29/2007 (revision 533476) that the commons jars were updated. OFBiz 4.0 seems to using the old commons-collections. Before I start replacing my commons jars, I wanted to see if anyone had any knowledge of this situation. -- View this message in context: http://ofbiz.135035.n4.nabble.com/random-high-cpu-utilization-tp2259392p2259392.html Sent from the OFBiz - Dev mailing list archive at Nabble.com.
