Subject CamelContext resume does not reactivate the route
Date Sat, 09 Mar 2013 01:23:40 GMT
Hello experts,

I have a route consuming from file endpoint and then other routes chained
downstream using direct:.

When I get a particular kind of exception, I want to be able to suspend the
CamelContext (camelContext.suspend). And then be able to resume the Context
from JMX. 

Now, what happens is that as soon as I issue "suspend context" from the
code, it goes through the defaultShutDownStrategy and logs these messages
for 300 seconds (expected).

*INFO.org.apache.camel.impl.DefaultShutdownStrategy:
org.apache.camel.impl.DefaultShutdownStrategy$ShutdownTask.run.523 Waiting
as there are still 5 inflight and pending exchanges to complete, timeout in
43 seconds.*

Not sure why the 5 inflight exchanges are not getting flushed out, but
eventually, times out and suspends the route. 

WARN.org.apache.camel.impl.DefaultShutdownStrategy:
*org.apache.camel.impl.DefaultShutdownStrategy.doShutdown.191 Timeout
occurred. Now forcing the routes to be shutdown now.

org.apache.camel.impl.DefaultShutdownStrategy$ShutdownTask.run.556 Route:

Endpoint[direct://suspendContext]


Even after I resume the context using JMX, my route-psp1 refuses to pick up
files from the input endpoint location.

Can somebody advice me as to what I am doing wrong? I am using Camel 2.10.3.

Thanks in advance
Rajesh
