In Seam I'm seeing "The conversation ended, timed out or was processing another request" or ConcurrentRequestTimeoutException or LockTimeoutException

Issue

• When I submit a page or hit submit button twice or more times in rapid succession I get the following error:

The conversation ended, timed out or was processing another request

• Receiving The conversation ended, timed out or was processing another request when accessing a page with conversation-required="true".

• When clicking an ajax button a few times I receive the exception:

org.jboss.seam.ConcurrentRequestTimeoutException: Concurrent call to conversation

• In my logs I'm seeing:

org.jboss.seam.core.LockTimeoutException: could not acquire lock on @Synchronized component: <;component>
