Kafka server not recognizing consumer thread is down

Hi, 

I am currently using kafka server 0.9 version. My kafka consumer version is 0.8.2.2. I run into cases where my kafka consumer thread is down (when I check the threaddump, I can see my kafka consumer thread is down), but the server still thinks the kafka consumer thread is up and doesn't reallocate those partitions to other kafka consumers. 

This results in lag in those partitions which are allocated to consumer threads which are down. Is there anything that I can do to resolve this?

Thanks,
Sriram
