[jboss-user] [JBoss Cache: Core Edition] - Re: Resident Nodes evicted in heavy load conditions

[mahendragoyal]

Hi Markus,

we have encountered the same issue again, following are the settings used

jboss.Transaction.IsolationLevel=NONE
jboss.clustered.CacheMode=LOCAL
jboss.policyClass=org.jboss.cache.eviction.LRUPolicy
jboss.evictionThread.wakeUpIntervalSeconds=600
jboss.region.products.maxNodes=300jboss.region.products.timeToLiveSeconds=14400
jboss.region.products.eventQueueSize=200000

Stack Trace
--------------
org.jboss.cache.NodeNotValidException: Node /Products is not valid.  Perhaps it has been moved or removed.

Like I told you earlier we store the "Product" node in a hashtable which is marked as resident in the begining after the creation
 
Lately in our performance tests the error was coming up in logs every few hours.

I am not sure how I can reproduce it since its very inconsistent.

Could you please help us a bit with this

Many Thanks,
mahendra
