Deadlock when creating containers

[fordm_martin.ford]

Hi,

I'm using Fuse 7.1.0 (fuse-71-047) and have found that I quite regularly get a deadlock between two threads (pool-org.apache.karaf.deployer.blueprint-2.3.0.fuse-71-047-thread-1 and FelixStartLevel).

Attached is part of the threaddump from Java VisualVM.

I've read posts elsewhere that suggest it could be related to attempting to install a number of features in fairly rapid succession (I'm creating around ten containers in a fabric, but I guess it's the total number of features that is important).

Has anyone come across this issue / have a suggestion for a work around?

Might installing the features before creating the containers help?

Many thanks

Are the created containers, child containers on the same box?

I think Fabric has had some improvements in that area which is rolled into the upcoming JBoss Fuse 6 release.

Though Ioannis who works a lot on Fabric is the best person to know this on top of his head.

Yes, all the containers are children of root and are on the same box. Which raises the question of whether there is a recommended limit on the number of containers one would create on a single box?

Any input from Ioannis would be gratefully received.
