> Hey Guys,
> I'm seeing a very strange bug after I upgraded to Kafka 0.7.14. On my
> consumer side, the process seems to run with very high CPU usage. I turned on
> HPROF, and it's showing that 75% of the CPU usage is going to Java's NIO
> EPoll/select calls.
> There are supposedly work arounds that Mina and a few others employ. This
> seems like more of a ZK bug- have you guys seen this before?
> Any ideas?
