Hi, I have a service using the C++ Messaging API which connects to a single instance of qpidd (currently on the same machine), which seems to crash out with this exception every couple of days under moderate load:
qpidd[68257]: 2015-04-28 11:56:38 [Broker] error qpid.192.168.2.225:5672-192.168.2.148:60492: resource-limit-exceeded: Maximum depth exceeded on b1386bee-a36c-449d-953f-c25f4842e76d_hive.guest.metadata_7bf9355b-524b-4853-89bd-1848366cd21f: current=[count: 389438, size: 104857546], max=[size: 104857600] (/build/buildd/qpid-cpp-0.28/src/qpid/broker/Queue.cpp:1575) Using qpid-stat I don't see the queue depth ever increase from 0 (which I gather is why the exception is thrown, from reading the code), however I -do- notice that the "acquired" count is increasing with every message with no corresponding "release" (release count is always 0). My service currently looks a lot like the "Receiving Messages from Multiple Sources" on this page: https://qpid.apache.org/releases/qpid-0.28/messaging-api/cpp/api/index.html, and I am definitely calling the message agnostic "session.acknowledge()" in my main event loop, so I'm not sure why the messages are never released (presuming that messages would be released about settling/acknowledgement). I've created a ticket for what I think is a bug in the broker here: https://issues.apache.org/jira/browse/QPID-6517, but figured I would post here as well just in case there is operator error happening on my part: Regards, Matt
