Alan Conway updated QPID-4144: ------------------------------ Attachment: thread-dump.txt Thread dump of the deadlocked process. > HA broker deadlocks on broeker::QueueRegistry lock and ha::Primary lock > ----------------------------------------------------------------------- > > Key: QPID-4144 > URL: https://issues.apache.org/jira/browse/QPID-4144 > Project: Qpid > Issue Type: Bug > Components: C++ Clustering > Affects Versions: 0.17 > Reporter: Alan Conway > Assignee: Alan Conway > Fix For: 0.18 > > Attachments: thread-dump.txt > > > Running tests repeatedly, the broker deadlocked with the attached stack trace. > The problem call sequences are: > 1. QueueRegistry::destroy takes QueuerRegistry lock > > ConfigurationObserver::queueDestroy > ha::Primary::queueDestroy takes Primary > lock. > 2. ConnectionObserver::opened cals Primary::opened lock> > RemoteBackup>getQueues().eachQueue > This patch breaks the deadlock at both ends: QueueRegistry no longer holds > the lock across the observer call and Primary does not hold the lock across > eachQueue. -- This message is automatically generated by JIRA.
