[infinispan-dev] NBST test failures in Query

I'm having a couple of tests in the Query module sporadically (but often) failing because of exceptions like: - Received invalid rebalance confirmation from NodeC-62354 for cache ___defaultcache, we don't have a rebalance in progress - Suspected members - WARN [InboundTransferTask] (transport-thread-1,NodeD) ISPN000210: Failed to request segments [0, 2, 4, 36, 6, 42, 8, 43, 40, 10, 41, 11, 12, 13, 14, 50, ... - ISPN000071: Caught exception when handling command CacheTopologyControlCommand ... Looks very much state-transfer related to me. Could anyone from the NBST experts have a look? There are some interesting test there: org.infinispan.query.distributed.MultiNodeDistributedTest and its extensions explicitly attempt to start additional nodes, scaling up and down while performing other operations. To be fair, I wish they would really do thinks in parallel, but they are politely blocking and waiting for rehashing to complete at each step.. I would expect at this point to see some tests doing operations and - in parallel - have nodes added and removed. Are there no such tests in core? Sanne
