[infinispan-dev] Possible Bug in Distribution Manager

Hi, My name is Pedro and I am working in CloudTM project. I think that I may have encountered a possible bug in the consistent hash function. I am working on Infinispan 'Pagoa' 5.0.0-SNAPSHOT with JGroups 3.0.0 Alpha1 and I have a total of 100 000 keys distributed by 11 nodes. I am using Radargun, that was modified to execute the maximum number of transactions in a 5 minutes run. All transactions updates at least one key, ie, I didn't have read-only transactions. At the end of the test, I am printing all the keys and their location (keys' owners), and, as you can see for instance here [1], different nodes have different opinions concerning which replicas are in charge of storing some keys. Note that I didn't change anything in the distribution code and my tests only update keys, never delete them. Part of the log can be found in [2] and the config file is in [3]. In the log file we have a lot of 'WARN [DistLockingInterceptor] xxx entry commit warmup_key(...) => Thread(...)'. Ignore this entries. Unfortunately, the problem does not always show up, in my tests this shows up, say, 5% of the times. Did this ever happen to you, or am I hitting a known issue? I hope that the information that I am providing can be sufficient to reproduce the bug, let me know if there is anything else that I can do to help....
