QPID-7373: force all EpollPoller threads to periodically clean DeletionManager
resources
> memory leak in broker with idle worker threads
> ----------------------------------------------
>
> Key: QPID-7373
> URL: https://issues.apache.org/jira/browse/QPID-7373
> Project: Qpid
> Issue Type: Bug
> Components: C++ Broker
> Affects Versions: qpid-cpp-0.34
> Environment: linux epoll and perhaps PosixPoller and Solaris ECFPoller
> Reporter: Cliff Jansen
> Assignee: Cliff Jansen
>
> If a C++ broker is lightly loaded with many short lived connections such that
> at least one worker thread remains unwoken from the epoll_wait, its
> DeletionManager::ThreadStatus::handles grows without bound and the associated
> handles retain a shared_ptr ref and never go away.
> To reproduce check RSS from ps (or malloc_stats) when running a simple
> program that creates a connection and nothing else:
> hex5: cat foo.cpp
> {code}
> #include <qpid/messaging/Connection.h>
> #include <iostream>
> using namespace qpid::messaging;
> int main(int argc, char** argv) {
> std::string broker = argc > 1 ? argv[1] : "127.0.0.1:5672";
> Connection connection(broker);
> try {
> connection.open();
> connection.close();
> return 0;
> } catch(const std::exception& error) {
> std::cerr << error.what() << std::endl;
> connection.close();
> return 1;
> }
> }
> {code}
> hex5: while true; do LD_LIBRARY_PATH=../rt/b/amqp/b/q35x/rt/lib64 ./foo ;
> done
