when using TNonblockingServer(with thread pool),I found a dead lock in high QPS status. The worker thread will call notifyIOThread when it finishes its work, then call TNonblockingIOThread::notify and wait for write event in poll without timeout. If there is a write event, worker thread will return and release threadManager->mutex; The IO thread will call addTask when it gets requests. And IO threads will lock the same mutex in addTask without a timeout, so IO thread can not write data to socket, there is a dead lock. I found there is no method to set a timeout of the locking operation in addTask. Is it a bug of thrift 0.12.0? -- This message was sent by Atlassian Jira (v8.3.4#803005)
