I tried to search the same reference in release docs as well but > did not get anything in 0.10.1.1 or 0.10.2.0. I am currently using > 2.11_0.10.2.0. > I am have 3 node cluster for KAFKA and cluster for ZK as well on the same set > of servers in cluster mode. We are having around 240GB of data getting > transferred through KAFKA everyday. What we are observing is disconnect of > the server from cluster and ISR getting reduced and it starts impacting > service. > I have also observed file descriptor count getting increased a bit, in normal > circumstances we have not observed FD count more than 500 but when issue > started we were observing it in the range of 650-700 on all 3 servers. > Attaching thread dumps of all 3 servers when we started facing the issue > recently. > The issue get vanished once you bounce the nodes and the set up is not > working more than 5 days without this issue. Attaching server logs as well. > Kindly let me know if you need any additional information. Attaching > server.properties as well for one of the server (It's similar on all 3 > serversP) -- This message was sent by Atlassian JIRA (v6.3.15#6346)
