---------------------------------------
Summary: AdminServer stops responding (possible deadlock)
Key: ZOOKEEPER-3702
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3702
Project: ZooKeeper
Issue Type: Bug
Components: server
Affects Versions: 3.5.6
Environment: CentOS 7.x, JDK 8 (various patch levels)
Reporter: Craig Condit
We have been running Zookeeper 3.5.6 on several clusters for a while now, and
have noticed (pretty consistently) that the new Admin Server seems to stop
responding (hangs) after the ZK service has been up and running for a while.
I'm not sure what causes this, but it seems to happen fairly reliably after
some time (sometimes 10 minutes or more). This manifests as curl (or any other
HTTP client) hanging while attempting to access any URL from the admin server
port, even the top level which normally just returns a generic Jetty 404 error.
Possibly this was triggered by a Jetty version update?
