> Hello Community!
> We need to advice on  the server failure cases which related to Jackrabbit Content repository
functionality.
> Almost all application server threads were waiting for ReaderLock or WriterLock (please
find attached LockStackTrace.txt). In addition to the Read-/WriteLock there was blocked thread
related to Jackrabbit cluster nodes functionality (please find attached ClusterNodeBlockStackttrace.txt).
> We have clustered environment and using the version of the Jackrabbit library as follows:
> concurrent-1.3.4.jar
> derby-10.2.1.6.jar
> jackrabbit-1.5.2-src.jar
> jackrabbit-api-1.5.0.jar
> jackrabbit-core-1.5.2.jar
> jackrabbit-jca-1.5.2.jar
> jackrabbit-jcr-commons-1.5.2.jar
> jackrabbit-spi-1.5.0.jar
> jackrabbit-spi-commons-1.5.0.jar
> jackrabbit-text-extractors-1.5.0.jar
> jcr-1.0.jar
> lucene-core-2.3.2.jar  
> The advice that we need:
> 1)	What could cause appearance of a Lock which prevent getting Reader-/WriterLock ?
> 2)	Can it be related to the blocked thread from ClusterNodeBlockStackttrace.txt ?(please
see attachments)
> We found that an update of GLOBAL_REVISION  table can take up to 30 min ("GLOBAL_REVISION"
- internal table name in Jackrabbit).  
> Is it  possible that this issue is related to the Read-\WriteLocks?  
> Thanks.
