This patch currently monitor collectible objects, and we may add other interesting stuff later if needed. To enable the monitor, you must set: [devel] health_monitor_enable = true In vdsm.conf, and restart vdsm. Here is an example logs - this was logged 60 seconds after starting vdsm, when running as spm: Thread-13::DEBUG::2016-01-14 18:53:43,239::health::84::health::(_check) Checking health Thread-13::DEBUG::2016-01-14 18:53:43,272::health::86::health::(_check) Collected 460 objects Thread-13::WARNING::2016-01-14 18:53:43,277::health::100::health::(_check) Found 5873 uncollectible objects, 10 suspects implementing __del__: ['<pthreading.Lock object at 0x7f012c115320>', '<pthreading.Lock object at 0x7f012c115440>', '<pthreading.Lock object at 0x7f012c1153b0>', '<pthreading.Lock object at 0x7f012c1154d0>', '<pthread.Cond object at 0x7f012c111350>', '<pthread.Cond object at 0x7f012c1112d0>', '<pthread.Cond object at 0x7f012c111250>', '<pthread.Cond object at 0x7f012c111850>', '<pthread.Cond object at 0x7f012c1117d0>', '<pthread.Cond object at 0x7f012c111750>'] We found 460 uncollectible objects, 10 of them are objects implementing __del__. Having such object in a reference cycle make the entire cycle uncollectible. The pthreading objects in this log grow as vdsm continue to run, even without any interaction with engine. The pthreading objects leak is caused by a cycle in storage.misc.RWLock, fixed in patch [2]. After solving the pthreading leak, we still have many uncollectible objects in the logs, listing them, it seems that the suspect is hiding inside a collection (dict, list, tuple) and does not appear in the gc.garbage list. I will address this in later patch, searching in the entire object graph instead of the top level of gc.garbage. See end of this mail for list of these objects. I printed them like this: Enable manhole debugging shell: [devel] manhole_enable = true Connect to vdsm using manhole: nc -U /run/vdsm/vdsmd.manhole Print garbage: >>> import pprint >>> import gc >>> with open('/tmp/garbage.txt', 'w') as f: pprint.pprint(gc.garbage, stream=f, indent=4) These objects looks related to libvirt - Francesco, can you take a look?

I tested with https://gerrit.ovirt.org/#/c/51630 libvirt.virDomain object does not leak any more, but pthreading object are still leaking, and the number of uncollectible objects is still very high (12,915). Each time we start and stop a vm, we leak about 6000 objects which are part of a reference cycle, and each time we create and leak 27 pthreading locks/conditions which are probably the reason for this leak (because they implement __del__ or reference object implementing __del__. When vdsm is idle, we leak 18 objects per minute, we don't know yet why. # tail -f /var/log/vdsm/vdsm.log | grep health Vdsm was connected to storage pool here, running as the spm...
