Sergey Kondratyev commented on ISPN-1127:
-----------------------------------------

Try to start the test and when test sleeps do
jmap -histo:live PID-HERE|grep org.infinispan.transaction.xa.GlobalTransaction
It shows 10k transaction objects for me (the same in memory dump if created).
Hope this helps.

> CacheStoreInterceptor leaks org.infinispan.transaction.xa.GlobalTransaction objects. Amount of live org.infinispan.transaction.xa.GlobalTransaction objects is climbing during cache work.
> It is possible due to two reasons:
> 1. when cache is in async replication mode entries from both txStores and preparingTxs are never deleted (maybe like JBCACHE-1454 ?).
> 2. when cache is in sync mode (I tested on dist sync mode), entries from preparingTxs are not deleted in commit method (in case no exceptions raise).
> So preparingTxs are never cleaned at all. Problem with txStores appears only with async mode.
