Sergei updated JCR-2618: ------------------------ Description: 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. was: Hello Community!
