> URL: https://issues.apache.org/jira/browse/MESOS-954
> Project: Mesos
> Issue Type: Bug
> Components: libprocess
> Reporter: Benjamin Mahler
>
> Looks like the processing of each event queue in __processes__ is lacking the
> needed lock acquisition:
> Future<Response> ProcessManager::__processes__(const Request&)
> {
> JSON::Array array;
> synchronized (processes) {
> foreachvalue (const ProcessBase* process, process_manager->processes) {
> ...
>
> // XXX: This processes the event queue but does not lock process.
> foreach (Event* event, process->events) {
> event->visit(&visitor);
> }
> object.values["events"] = events;
> array.values.push_back(object);
> }
> }
> return OK(array);
> }
