We’re seeing an issue with the ehCache extension (using a manual replication configuration) where very occasionally a node will miss it’s instructions to expire the cache. It seems to be very intermittent but I’m trying to track down the root cause.
I want to enable debug logging so I can try to at least determine what happened when we see an instance where a node has failed to update the cache.I should be able to enable this debugging by setting the log4j/log4j2
net.sf.ehcache.distribution.RMICachePeer logger to
I should know this, but how would I set the logging properties so the extension will pick it up?
The docs indicate that you should be able to put a log4j.properties file in the
/lib folder of Tomcat.
Does that still hold true?
I assume we’d actually need to use the
log4j2.xml now that Lucee is running log4j2.
My feeling is I’m probably running into a race condition in ehCache, similar to what’s described here:
So there might not be a resolution, without changing the distributed caching mechanism.
