Hi Manuel
If you have the possibility to upgrade and test in a non-production environment, this
would be preferable. AS 7.1.3 is a bug fix release (containing fixes to some 400 issues,
including the current issue). Your installation would also benefit from those extra fixes;
the chances that those additional bugs fixes would raise yet further issues is small,
although I can't guarantee that no additional issues would not arise.
However, if you don't feel comfortable with that option, I have attached the patch for
fix AS7-4260 in the file AS7-4260.patch. You can download AS 7.1.1 from GitHub, apply the
patch and then rebuild to create a new AS 7.1.1 binary with the patch included. I have
done this, ran the AS 7.1.1 testsuite (including clustering tests) and the testsuite
passes.
1. Download AS 7.1.1 sources as a zip file from here:
https://github.com/jbossas/jboss-as/tree/7.1.1.Final (just click on the Zip icon to
download the zip file)
2. Unzip the zip file, creating a directory jboss-as-7.1.1.Final
3. Apply the attached patch - I use Linux patch and would do the following:
cd jboss-as-7.1.1.Final
patch -p1 < /tmp/AS7-4260.patch
4. Rebuild AS 7.1.1
cd jboss-as-7.1.1.Final
./build.sh clean install
5. Pick up the modified AS 7.1.1.Final binary which is located at
jboss-as-7.1.1.Final/build/target/jboss-as-7.1.1.Final
Let me know if you have any issues.
Cluster Environment Web Session Locks
-------------------------------------
Key: AS7-6397
URL: https://issues.jboss.org/browse/AS7-6397
Project: Application Server 7
Issue Type: Bug
Components: Clustering
Affects Versions: 7.1.1.Final
Environment: Windows 7 64bits, 8 GB RAM
Reporter: Manuel Pinto
Assignee: Paul Ferraro
Attachments: AS7-4260.patch
Hi,
I found a problem with web session locks in a cluster environment. We have two Liferay
6.1.1 nodes (over JBoss 7.1.1 Final) in standalone-ha.xml configuration with infinispan
"web" cache-container, replicated-cache and file store. The load balancer is
configured in non sticky session mode.
Problem: when a node processes requests in some cases locks the session and never unlock
it, preventing other node from processing requests for that session. The affected node
never regain the locked session and keep throwing the following exception for all
subsequent requests and only recover a session when other node shutdown:
Note: we also tried invalidation-cache and distributed-cache and all locking modes but
without success.
