Subject [jira] Commented: (AMQ-643) maxInactivityDuration does not seem to work properly
Date Tue, 21 Mar 2006 04:45:26 GMT

Hiram Chirino commented on AMQ-643:

Hi Kevin,

Yeah, I agree, making sure everybody is using the same setting is a bit of a problem.  I working
on a change right now that will allow the setting to be negociated by the 2 sides of the connection
when it's initialy established.

If the server setting is x and the client setting is y, then the inactivity duration for the
established connection will be calculated at min(x,y).  This way the client and server do
not have to have their configs match up exactly.

I'll update the issue once the change is commited.

> Using maxInactivityDuration causes a connection to automatically break after the inactivity
duration, even though nothing is wrong with either side of the connection.
> Tracing it through, it looks like the KeepAliveInfo command does not require a response.
 This means that the KeepAlive sent never results in receive activity.  So, if both processes
are perfectly fine, just not sending any data, the connection breaks due to InactivityMonitor.readCheck.
> I've changed to return true for isResponseRequired.  This seems to
fix the problem, from a client perspective, anyway.
> However, if this is used for broker-to-broker connections, and you force a problem with
one of the brokers (like doing pstop on Solaris), major problems will happen:
> 1)  The broker that is left alone seems to break the connection.  But, it continues to
attempt to send messages to the failed broker.  It was mentioned in the forum at one point
you were going to have the broker unregister subscriptions so it would not attempt to send
messages to the failed broker.  Doesn't seem like this is in place.
> 2) If you reawaken the pstopped broker, the two brokers never really recover properly.
 Connections continue to get broken, over and over again.
