> TNonblockingServer and TThreadedSelectorServer do not close their channel
> selectors on exit and do not release all ressources.
> This is an issue especially when such server implementations are started and
> stopped repeatedly within the same JVM. In our use case, we see hundreds of
> file descriptors being leaked on each Thrift server restart. We hit the OS
> limit on the number of open files pretty quickly.
> The attached patch fixes the issue by simply calling Selector.close() when
> the relevant select threads exit (TNonBlockingServer::SelectAcceptThread,
> TThreadedSelectorServer::SelectorThread,
> TThreadedSelectorServer::AcceptThread)
