Description

we are seeing an issue were we intermittently (every couple of hours) get and error with certain topics. They stop working and producers give a LeaderNotFoundException.
When we then try to use kafka-topics.sh to describe the topic we get the error below.

Error while executing topic command : next on empty iterator

}}

if we delete the topic, then it will start to work again for a while
We can't see anything obvious in the logs but are happy to provide if needed
