xiaokang commented on THRIFT-1653:
----------------------------------
the reason about creating this bug maybe is in
lib/cpp/src/thrift/transport/TBufferTransports.h line 230~231. If flush throw a
exception, then transport have no chance to close, so the socket don't do the
close, that is make CLOSE_WAIT sockets
> TThreadedSelectorServer leaks CLOSE_WAIT sockets

>
> We are using TThreadedSelectorServer in HBase regionserver. We are observing
> that under high load thousands of sockets in the CLOSE_WAIT state are not
> being cleaned up, leading to server crash. Is it possible that the sockets
> are not being closed on the server side, or the process of closing sockets
> closed by client is being starved on the server, because normal I/O takes
> priority?
