Hi,
From the stack trace , it looks like you are still using Camel 1.x.
It looks like the camel timer thread is blocked by CountingLatch.
So I doubt if the async processor thread has some kind of dead lock with
other thread.
Maybe you can work around it by increasing the timer's period time.

Hi,
I'm using Camel with ServiceMix4 (Fuse ESB) and I have problem with timer
component.
From time to time my timer's thread stops. A thread dump is following:
Name: timer:foo?period=5000
State: WAITING on

Where is the problem? Maybe too many threads is created?
