This "jgroups" backend was there "long" ago.
And it was actually us - CD - that fixed it and made use of it.
It's no different from static JGroups backed, the only diff that this one elects master automatically.

I can change to Sanne's new Ispn based prototype if it will help.

But - with my limited cluster knowledge - the issue doesn't look to be there.
I mean, the msgs get properly routed to indexing master, which just cannot handle locking contention.

Any thoughts on this, Sanne?

I believe this new backend is WIP in Hibernate Search.  Sanne, didn't you have a prototype in Infinispan's codebase though?

are you not using the JGroups backend anymore?

I'm using that "jgroups" backend, with auto-master election.

these Lock acquisitions are on the index lock, and make me suspect your configuration is no longer applying the pattern we discussed a while back, when you contributed the fixed to the JGroups indexing backend.

Or is it the "Replication timeout for mstruk/capedwarf" which is causing those locking errors?

No idea.

btw: didn't you say you had some new backend mechanism?
Off Infinispan's channel.

We're running a GAE HelloOrm2 example app on 3 nodes (3 laptops).

Very soon after deploy, we get a never-ending stack of timeouts,
which completely kills the app:

I then need to kill the AS in order to get it shutdown.

How can this be tuned / fixed?
