    [ https://issues.apache.org/jira/browse/ZOOKEEPER-1347?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14051448#comment-14051448 ] 

Bill Havanki commented on ZOOKEEPER-1347:
-----------------------------------------

It appears this was fixed as part of ZOOKEEPER-1504. The HashSet in ServerCnxnFactory was replaced with a concurrent set.

> Cnxns is currently stored as a HashSet but may be accessed by multiple threads concurrently. Instead of doing our own sync we should investigate using a proper concurrent data structure for this.
