Hi team,
Recently we see JVM stuck , in stack trace I can see below method having problem
As per document
From link :
https://geode.apache.org/releases/latest/javadoc/org/apache/geode/cache/CacheListener.html
this warning:
WARNING: To avoid risk of deadlock, do not invoke CacheFactory.getAnyInstance()
from within any callback methods. Instead use EntryEvent.getRegion().getCache()
or RegionEvent.getRegion().getCache()
What is the best solution to avoid it.
