when does storm kill a bolt?

[Babar Ismail <ba...@microsoft.com>]

Hi!

I have a topology in which the spout emits a "Hello World" tuple and the bolt writes that tuple to kafka.

I notice that in certain cases, storm will kill the bolt and restart it on a different supervisor but I have been unable to determine what causes storm to kill a bolt.

Is it when the bolt consumes too much memory? Is it when the bolt lags too far behind the spout? Or is there any other configuration setting that causes this?

Any help will be appreciated.

Thanks,
Babar
