Error loop

Hi,

I have a situation where I was testing a service that ran out of memory (which was fine), the problem I had is that my log file starting filling up with the following
Occurring I a loop (See below), it seems the leader selector threw an exception – but instead of being pushed up the stack, it is caught and the same operation
retried … which causes the log file to blow up. Not sure how to resolve this, anyone have ideas?


Regards,
Mike Lewis

RE: Error loop

Posted by Mike Lewis <ML...@nephilaadvisors.co.uk>.
I forgot to add that when starting my service, I am calling ‘autoRequeue’ on the LeaderSelector, possibly I’m not dealing with Curator events correctly…
