Re: RabbitMQ annoying disconnections [kolla-ansible, rabbitmq]
Hi, I’ve tried to set heartbeat_in_pthread = true, but nothing has changed after kolla-ansible reconfigure - still got disconnections and heartbeat_in_pthread option was present inside configs on all nodes. But in the meantime I tried to alternate rabbit configuration and I realized that Kolla ignored /etc/kolla/config/rabbitmq.conf file (of course at first I checked permissions, etc.) So I tried to put heartbeat = 600 inside /etc/kolla/config/rabbitmq/rabbitmq.conf - this overwrote rabbitmq.conf totally (I mean Kolla didn’t just add heartbeat = 600 to rabbitmq.conf on each controller node, but put ONLY this line in all rabbitmq.conf files ! - rest of the file was cleared). So finally I tried to create separate config for each controller node. So I copied default content of /etc/kolla/rabbitmq/rabbitmq.conf on each controller (because of course these files differs from each other - they have different IPs inside) to /etc/kolla/config/rabbitmq/controller1(2,3)/rabbitmq.conf And finally heartbeat = 600 started to work - no more disconnections. I left Oslo heartbeats and timeouts intact (with the values I’ve set previously) and I don’t have disconnections from services side too. So there are two questions: 1. Why heartbeat_in_pthread didn’t change situation? And if it’s deprecated it was kind of risky to use it long term (after upgrade to wallaby it would stop working anyway?) 2. Why Kolla-ansible ignored rabbitmq.conf file if it is located in /etc/kolla/config, and overwrites ALL content of rabbitmq.conf file when it is located in /etc/kolla/config/rabbitmq/ ?

[oslo_messaging_rabbit] heartbeat_in_pthread = True
But for Victoria (nova sample configuration file) it seems to be deprecated? # DEPRECATED: Run the health check heartbeat thread through a native python # thread by default. If this option is equal to False then the health check # heartbeat will inherit the execution model from the parent process. For # example if the parent process has monkey patched the stdlib by using # eventlet/greenlet then the heartbeat will be run through a green thread # (boolean value) # This option is deprecated for removal. # Its value may be silently ignored in the future. #heartbeat_in_pthread = true So will it work?
Yes it will work.
Few months ago I proposed to remove this deprecation and to keep the option available [1], unfortunately my removal isn't yet merged. Only the default value is changed and the option will be turned on by default.

This sounds like you're hitting the heartbeat/eventlet bug. Basically eventlet won't schedule the heartbeat thread unless something is regularly waking up the api threads. Depending on what release you're running, you may be able to set heartbeat_in_pthread[0] to fix this.

Hi, after some struggling I have almost „clear” logs (clear=error free :) ) Almost…. RabbitMQ keeps disconnecting sessions and there is a huge amount of disconnect errors in all logs (see below). I found this bug description: https://bugzilla.redhat.com/show_bug.cgi?id=1711794 <https://bugzilla.redhat.com/show_bug.cgi?id=1711794> <https://bugzilla.redhat.com/show_bug.cgi?id=1711794 <https://bugzilla.redhat.com/show_bug.cgi?id=1711794>> in which we can read as follows: "this is a recoverable issue that is already handled by how oslo.messaging is designed. disconnection is not an error and should not be reported as such in the logs.” but… It is reported :( And produces tons of logs. I tried to modify heartbeat values - helped a little bit, but I had to increase [database] max_pool_size = 5 and that of course multiplied number of disconnection errors by 5 :( [oslo_messaging_rabbit] heartbeat_timeout_threshold = 720 heartbeat_interval = 360 heartbeat_rate = 4 How to avoid this disconnections?? Or what to do to avoid writing this „errors”to logs?

So there are two questions:
1. Why heartbeat_in_pthread didn’t change situation? And if it’s deprecated it was kind of risky to use it long term (after upgrade to wallaby it would stop working anyway?)
It's deprecated because it became the default behavior in subsequent releases. The functionality is not going away, just the ability to turn it off. The only reason it was ever configurable was that we had concerns about mixing pthreads and greenthreads and wanted the people affected by the original bug to test the combination for a couple of releases before we turned it on for everyone.

actully the ablity to trun it off is not going away either turing it on can break the nova comptue agent by breaking eventlet. https://bugs.launchpad.net/oslo.messaging/+bug/1934937 here is the patch to undeprecate it https://review.opendev.org/c/openstack/oslo.messaging/+/800621 based on the bug above this looke like it should be turned off unless you runing under mod_wsgi or uwsgi where the pthread is needed to escape there treadign lifecycle.

Ah, okay. I thought I remembered seeing some discussion about that but I missed the patch. +2.
Well, then see what I have in impl_rabbit.py (kolla-ansible 11, newest container images, Victoria): cfg.BoolOpt('heartbeat_in_pthread', default=False, help="EXPERIMENTAL: Run the health check heartbeat thread " "through a native python thread. By default if this " "option isn't provided the health check heartbeat will " "inherit the execution model from the parent process. By " "example if the parent process have monkey patched the " "stdlib by using eventlet/greenlet then the heartbeat " "will be run through a green thread."), 1. It is disabled by default, so heartbeats run through green thread? 2. Why enabling it didn’t change anything? 3. heartbeat = 600 for rabbit resolved problem for now (but I’ve seen 1-2 timeouts after 2 days anyway), but 10-minute timeout is kind of big, so I would like to use another solution Best regards Adam Tomas
