Andrey Gura commented on IGNITE-1233:
-------------------------------------
During debug I found out that some entries is not removed from
{{GridCAcheAdapter.map}} on some/all nodes. In this cases map contains entries
with old values. I'll try find the cause of this behavior.
> Some tests derived from GridCacheAbstractRemoveFailureTest class fail
> sometimes

> Some tests derived from {{GridCacheAbstractRemoveFailureTest}} class fail
> sometimes. Most stable failures thre are in the following tests (accordingly
> to failure probability):
> *
> {{org.apache.ignite.internal.processors.cache.distributed.dht.GridCacheDhtClientRemoveFailureTest}}
> *
> {{org.apache.ignite.internal.processors.cache.distributed.near.GridCacheNearRemoveFailureTest}}
> *
> {{org.apache.ignite.internal.processors.cache.distributed.dht.GridCacheDhtRemoveFailureTest}}
> This problem was found during fixing IGNITE-1175 ticket. It seams that there
> is concurrency issue that leads to failures.
