["James E. King, III (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/THRIFT-3753?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15224992#comment-15224992 ] 

James E. King, III commented on THRIFT-3753:
--------------------------------------------

If you interrupt serve() second, a new client might arrive while the first set of clients is being interrupted; will the new client also be interrupted?

> This is a sequence that exposes the race condition:
> (1) Thread-1: in serve(), blocked on accept()
> (2) Thread-2: in stop(), calls interrupt()
> (3) Thread-2: in stop(), in interruptChildren(), checked that socket is valid
> (4) Thread-1: in serve(), unblocked because of interrupt(), calls releaseOneDescriptor
> (5) Thread-2: in interruptChildren(), send fails so clients are not interrupted
