Re: Getting rid of inflight changes

[bigandyt <an...@gmail.com>]

Hi Claus, 

Earlier you mention there was a bug shutting down the SEDA queues, are you
able to tell me what version it was fixed.

Im investigating an issue where some messages seem to be hung on a seda
queue and as we use quite an old version of camel im wondering if it could
be that.

Re: Getting rid of inflight changes

Ah thanks both for your replies, to be honest I was being a bit lazy and
should have looked at the changelogs, until recently we were limited with
the version we could use we are back at 2.5, we are updating an exisitng IBM
java 1.5 based application and integrating camel to help scale it out. Weve
now upgraded to 1.6 java so I will look into upping the Camel version also.

Its difficult to diagnose as we only see this issue on the production
environment, the messages just seem to sit on the queue and dont get
processed, I suspect its more environment related than camel but I think due
to the significant improvements between the version of camel we use and the
current I think its worth updating.

Thanks for your help

Hi,

Yes, this has happened to me with older versions of Camel. AFAIR, even
2.8.0 suffers from this. Newer versions are able to interrupt the thread
during shutdown.

Do you see a message like "nnn messages in flight. Waiting 300 seconds
before forcing shutdown." or something similar?

I suggest you look at the release notes.
You can also try the commit logs for the changes in
camel-core/src/main/java/org/apache/camel/component/seda - and if
anything rings a bell.

Possible. It depends what you mean by hung. Are you shutting down Camel,
and then some messages on seda queues, are not being processed, during
the graceful shutdown?
