Vishal K commented on ZOOKEEPER-880: ------------------------------------ Hi flavio, Ideally, I would like to have 932 part of 3.3.3 as well. But since 932 is not a blocker (and not approved yet), I understand if it doesn't get in 3.3.3. The order/dependency of patches that you have described is correct. Patch for 932 in a way depends on 880, but it will override 880 since it includes a fix for 880 as well. So we won't have to do any additional "merge" of 880 with 932. We will first commit 880 and then 932 to trunk. Also, I think patch for 900 needs to go in 3.3.3. > QuorumCnxManager$SendWorker grows without bounds > ------------------------------------------------ > > Key: ZOOKEEPER-880 > URL: https://issues.apache.org/jira/browse/ZOOKEEPER-880 > Project: ZooKeeper > Issue Type: Bug > Affects Versions: 3.2.2 > Reporter: Jean-Daniel Cryans > Assignee: Vishal K > Priority: Blocker > Fix For: 3.3.3, 3.4.0 > > Attachments: TRACE-hbase-hadoop-zookeeper-sv4borg9.log.gz, > ZOOKEEPER-880.patch, ZOOKEEPER-880.patch, ZOOKEEPER-880.patch, > hbase-hadoop-zookeeper-sv4borg12.log.gz, > hbase-hadoop-zookeeper-sv4borg9.log.gz, jstack > > > We're seeing an issue where one server in the ensemble has a steady growing > number of QuorumCnxManager$SendWorker threads up to a point where the OS runs > out of native threads, and at the same time we see a lot of exceptions in the > logs.
