-------------------------------------
Summary: Stopping Fuseki under Tomcat seems not to remove tdb and
lucene locks
Key: JENA-1136
URL: https://issues.apache.org/jira/browse/JENA-1136
Project: Apache Jena
Issue Type: Bug
Components: Fuseki
Affects Versions: Fuseki 2.4.0
Environment: CentOS 5.x
Reporter: Joachim Neubert
When restarting Tomcat with the latest Fuseki snapshot
(apache-jena-fuseki-2.4.0-20160209.095958-47.tar.gz), the application can't be
started:

locked by the process with PID 23588. TDB databases do not permit concurrent
usage across JVMs so in order to prevent possible data corruption you cannot
open this loc
ation from the JVM that does not own the lock for the dataset

After manually deleting all tdb.lock files, it barks on the text indexes:

org.apache.lucene.store.LockObtainFailedException: Lock obtain timed out:
NativeFSLock@/opt/thes/var/stw/9.0/tdb_lucene/write.lock
After deleting these manually, too, Fuseki starts. (So I've added the cleanup
temporarily to my tomcat stop function in the service definition file.)
