Qiao Mu created THRIFT-2872: ------------------------------- 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
