Jason Harvey updated CASSANDRA-6546:
------------------------------------
Summary: disablethrift results in unclosed file descriptors (was:
disablethrift followed by enablethrift results in unclosed file descriptors)
> disablethrift results in unclosed file descriptors
> --------------------------------------------------
>
> Key: CASSANDRA-6546
> URL: https://issues.apache.org/jira/browse/CASSANDRA-6546
> Project: Cassandra
> Issue Type: Bug
> Reporter: Jason Harvey
> Priority: Minor
>
> Disabling thrift and then re-enabling thrift results in unclosed thrift
> sockets being left around.
> Steps to reproduce:
> 1. Have a handful of clients connect via thrift.
> 2. Disable thrift.
> 3. Enable thrift, have the clients reconnect.
> 4. Observe netstat or lsof, and you'll find a lot of thrift sockets in
> CLOSE_WAIT state.
> * Also verifiable in
> org.apache.cassandra.metrics:type=Client,name=connectedThriftClients MBean.
> What's extra fun about this is the leaked sockets still count towards your
> maximum RPC count. As a result, toggling thrift enough times will result in
> an rpc_max_threads number of CLOSED_WAIT sockets, with no new clients able to
> connect.
