Affects Versions: 1.5.2, 1.5.0
Environment: Suo OS, Oracle DB, SAP AS
Reporter: Sergei
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)
