-----------------------------------------------------------------------------------------------------
Key: JBCACHE-1356
URL: http://jira.jboss.com/jira/browse/JBCACHE-1356
Project: JBoss Cache
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: Eviction
Affects Versions: 2.0.0.GA
Environment: JDK 1.6.0_5
Reporter: Anton Spirkov
Assigned To: Manik Surtani
We constantly receive the following message under load (~500 TPS):
[org.jboss.cache.RegionImpl] putNodeEvent(): eviction node event queue size is at 98%
threshold value of capacity: 200000 Region: / You will need to reduce the
wakeUpIntervalSeconds parameter.
However we have reduced the wakeUpIntervalSeconds to 1. This is a snapshot from our
configuration:
<attribute name="CacheMode">LOCAL</attribute>
<!-- Max number of milliseconds to wait for a lock acquisition -->
<attribute name="LockAcquisitionTimeout">15000</attribute>
<!-- Specific eviction policy configurations. This is LRU -->
<attribute name="EvictionPolicyConfig">
<config>
<attribute
name="wakeUpIntervalSeconds">1</attribute>
<attribute
name="policyClass">org.jboss.cache.eviction.LRUPolicy</attribute>
<!-- Cache wide default -->
<region name="/_default_">
<attribute name="maxNodes">50000</attribute>
<attribute
name="timeToLiveSeconds">1000</attribute>
</region>
</config>
</attribute>
