Subject Re: Kahadb reach storage limit then producers turn "idle"
Date Wed, 08 Oct 2014 08:08:37 GMT

I'd say you are running into flow control.

With configuration you can achieve that you get an exception if your 
storage is full, for example:

|||<systemUsage sendFailIfNoSpace="||true||">|
|||<memoryUsage limit="||20| |mb"/>|

You can also decide to throw the exception only after a given timeout, 
so your producers would wait a bit
whether space becomes available again and only throw the exception if 
the timeout is exceeded.

Hope that helps
