[rabbitmq-discuss] Recurring partitioning problem on local network

One of our sets went down today

Both nodes basically have this, just naming the other node:

=INFO REPORT==== 10-Dec-2013::18:29:24 ===
rabbit on node 'rabbit at NURWEB-QAWEB01' down

=ERROR REPORT==== 10-Dec-2013::18:29:35 ===
Mnesia('rabbit at NURWEB-QAWEB02'): ** ERROR ** mnesia_event got {inconsistent_database, running_partitioned_network, 'rabbit at NURWEB-QAWEB01'}

=INFO REPORT==== 10-Dec-2013::18:29:47 ===
node 'rabbit at NURWEB-QAWEB01' down: connection_closed

Not much more info with the patched base file... does this help at all?

I tried searching and got a lot on connection closed abruptly... but it did not sound right.

I've attached a modified rabbit_node_monitor.beam which can replace the one in your RabbitMQ installation's ebin directory. This version has been modified to additionally log messages on node down like this:

> =INFO REPORT==== 10-Dec-2013::16:32:02 === node hare at smacmullen down: 
> connection_closed

giving the reason why the runtime considers the other node to be down. 
(This feature will make its way into a future release eventually). I am curious as to whether you are really seeing net_ticktime-related timeouts or something else, and it would be good to get some data on that.

Cheers, Simon
