--------------------------------------
Summary: Socket leak in QuorumCnxManager connectOne
Key: ZOOKEEPER-2442
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2442
Project: ZooKeeper
Issue Type: Bug
Components: quorum, server
Affects Versions: 3.5.1
Reporter: Michael Han
Assignee: Michael Han
The function connectOne() in QuorumCnxManager.java sometimes fails to release a
socket allocated by Socket():
{code}
try {
if (LOG.isDebugEnabled()) {
LOG.debug("Opening channel to server " + sid);
}
Socket sock = new Socket();
setSockOpts(sock);
sock.connect(self.getView().get(sid).electionAddr, cnxTO);
if (LOG.isDebugEnabled()) {
LOG.debug("Connected to server " + sid);
}
initiateConnection(sock, sid);
} catch (UnresolvedAddressException e) {
// Sun doesn't include the address that causes this
// exception to be thrown, also UAE cannot be wrapped cleanly
// so we log the exception in order to capture this critical
// detail.
LOG.warn("Cannot open channel to " + sid
+ " at election address " + electionAddr, e);
throw e;
} catch (IOException e) {
LOG.warn("Cannot open channel to " + sid
+ " at election address " + electionAddr,
e);
}
{code}
