             Summary: ThreadManager deadlock for task expiration
                 Key: THRIFT-2872
                 URL: https://issues.apache.org/jira/browse/THRIFT-2872
             Project: Thrift
          Issue Type: Bug
          Components: C++ - Library
            Reporter: Qiao Mu


I have a TNonblockingServer running with 1 worker thread and 10 IO thread.

If there is a big task running, all pending tasks will be expired. In such 
case, all IO thread are waiting for maxMonitor_, but the worker won't notify 
because it will remove all the tasks(all of them are expired) first and 
tasks_.empty() will be true. Deadlock occurs.

The patch move the inner notify if clause out so it will notify even if all 
tasks are removed for expiration.
