Attached are a thread dump and list of 100 tenants you can copy/paste to
org.amdatu.core.tenant.cfg to reproduce the issue.
Marcel; can you take a look at this issue?
> Deadlock when creating many tenants from ConfigAdmin

> Key: AMDATU-314
> URL: http://jira.amdatu.org/jira/browse/AMDATU-314
> Project: Amdatu
> Issue Type: Bug
> Components: Amdatu Core
> Affects Versions: 0.1.1
> Reporter: Ivo Ladage - van Doorn
> Assignee: Ivo Ladage - van Doorn
> Fix For: 0.1.1
>
>
> If you create many tenants (i.e. 100) at once by adding the tenant
> configuration to the org.amdatu.core.tenant.cfg file in the /deploy
> directory, it ends up quite soon in some kind of deadlock situation. The
> dashboard is not accessible anymore and it doesn't create more then just a
> few tenants.s
