Kirk Lund updated GEODE-4748: ----------------------------- Description: Geode cache became inconsistent in case if -networking- serialization problems occur at commit time. How to reproduce: # create any simple _replicated_ region # run two nodes # put some value in the region (within a transaction or not) # execute query on both nodes to check that the same value is returned (I used JMX for that) # emulate somehow temporary -networking- serialization error (I changed the code throwing IOException from toData()) # repeat [#3], exception should occur # repeat [#4] - you should see different values on different nodes It looks like errors occurred after {{TXState.applyChanges}} produce inconsistency - it is impossible to rollback applied local changes what leads to the state where local cache contains changed data but other node(s) old data (before changes made in transaction). To me, consistency is a key property for the systems like Geode so I would consider this bug as a critical one. was: Geode cache became inconsistent in case if -networking- serialization problems occur at commit time.
