Hi,

in an eight node cluster setup with a distributed cache I get the following exception. The exception repeats for every Put until I restart the node.

org.infinispan.statetransfer.StateTransferInProgressException: Timed out waiting for the state transfer lock, state transfer in progress for view 43

[..]

The relevant StateTransferLockImpl object has runningWritesCount == 0 and writesBlocked == true. My cache configuration looks like this.

<namedCache name="distributed">

    <jmxStatistics enabled="true" />

    <clustering mode="dist">

        <stateTransfer fetchInMemoryState="false" timeout="20000" />

        <async />

    </clustering>

    <locking isolationLevel="READ_COMMITTED"

        lockAcquisitionTimeout="15000" useLockStriping="false" />

    <eviction maxEntries="10000" strategy="LRU" />

    <expiration maxIdle="3600000" wakeUpInterval="5000"/>

    <storeAsBinary storeKeysAsBinary="true" storeValuesAsBinary="false" enabled="false" />

</namedCache>

I do not see any obvious problems. There is no high load or a network issue. I know that the exception is expected after a node joins. But it should stabilize after a while. Anything I can do to fix this?
