JCS Hangs on server shutdown.

[Scott Archer]

I'm having trouble with a JCS thread hanging when we shutdown our tomcat
server.

Full thread dump Java HotSpot(TM) Client VM (11.0-b15 mixed mode, sharing):

"DestroyJavaVM" prio=10 tid=0xb4ba2400 nid=0x2888 waiting on condition

        at java.lang.Thread.run(Thread.java:619)

....


This is my auxillary cache config:

jcs.auxiliary.DC=org.apache.jcs.auxiliary.disk.indexed.IndexedDiskCacheFactory
jcs.auxiliary.DC.attributes=org.apache.jcs.auxiliary.disk.indexed.IndexedDiskCacheAttributes
jcs.auxiliary.DC.attributes.DiskPath=/jcs
jcs.auxiliary.DC.attributes.MaxPurgatorySize=500000
jcs.auxiliary.DC.attributes.MaxKeySize=500000
jcs.auxiliary.DC.attributes.OptimizeAtRemoveCount=300000
jcs.auxiliary.DC.attributes.MaxRecycleBinSize=7500
jcs.auxiliary.DC.attributes.OptimizeOnShutdown=false

We are calling:
CompositeCacheManager.getInstance().shutDown();
in the contextDestroyed method of our ContextListener. (webapp)


Any ideas or suggestions?
I'll be glad to give you more info if needed.


Thanks!
