Camille Fournier commented on ZOOKEEPER-1100: --------------------------------------------- I'm reviewing this issue. Can I get some clarity? Is the issue that you get a runtime exception outside of the try block after while (state.isAlive()) so the thread dies and hangs? Why put the try block there instead of around the entire method? > Killed (or missing) SendThread will cause hanging threads > --------------------------------------------------------- > > Key: ZOOKEEPER-1100 > URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1100 > Project: ZooKeeper > Issue Type: Bug > Components: java client > Affects Versions: 3.3.3 > Environment: > http://mail-archives.apache.org/mod_mbox/zookeeper-user/201106.mbox/%3Citpgb6$2mi$1...@dough.gmane.org%3E > Reporter: Gunnar Wagenknecht > Assignee: Rakesh R > Fix For: 3.5.0 > > Attachments: ZOOKEEPER-1100.patch > > > After investigating an issues with [hanging > threads|http://mail-archives.apache.org/mod_mbox/zookeeper-user/201106.mbox/%3Citpgb6$2mi$1...@dough.gmane.org%3E] > I noticed that any java.lang.Error might silently kill the SendThread. > Without a SendThread any thread that wants to send something will hang > forever. > Currently nobody will recognize a SendThread that died.
