(caveat - was having this issue with 0.10.0 but thought an update might help)
App has a simple layout: consume -> aggregate -> output to 2nd topic Starting the app I see pages of this sort of message: DEBUG org.apache.zookeeper.ClientCnxn - Got ping response for sessionid: 0xb58abf2daaf0002 after 0ms These repeat every 10 seconds until the app runs out of memory and gets killed by the OS. Watching the system from another window I can see the `/tmp/kafka-streams/<app>` space slowly consume many 10s of Gb. (> 60Gb when it finally crashed). IO wait jumps around quite a bit but often exceed 20%. Any thoughts on what I might have misconfigured in my cluster or my app? I have some other (standard) producers and consumers but this one KStream-based app is really struggling.
