Hi, all, We have recently encountered a Cassandra OOM issue when Cassandra is brought up sometimes (but not always) in our 4-node cluster test bed.
After analyzing the heap dump, we could find the Internal-Response thread pool (JMXEnabledThreadPoolExecutor) is filled with thounds of 'org.apache.cassandra.net.MessageIn' objects, and occupy > 2 gigabytes of heap memory. According to the documents on internet, it seems internal-response thread pool is somewhat related to schema-checking. Has anyone encountered similar issue before? We are using Cassandra 2.0.17 and JDK 1.8. Thanks in advance! Sincerely, Michael Fong
