Hi. I have problem with send data to my zabbix-server from the rabbitMQ server. On the rabbitMQ server i have more than 3000 queues. I've enabled debug and in logs i see:

...
2020-02-11 15:54:47,479 DEBUG: Discovered queue //na-vcpriv-qel-collector-id-ePhoto-UserPhoto
2020-02-11 15:54:47,479 DEBUG: Discovered queue na-vcpri-qel-collector-id-ePhoto-UserPhotoRemoved, checking to see if it's filtered...
2020-02-11 15:54:47,479 DEBUG: Discovered queue //na-vcpri-qel-collector-id-ePhoto-UserPhotoRemoved

2020-02-11 15:54:47,479 DEBUG: Discovered queue na-vcpri-qel-collector-id-ePpc-adgroup, checking to see if it's filtered...
...

And after that, by about 5-6 minutes, i see:

...
2020-02-11 16:01:12,898 DEBUG: Finished sending data

I've done all recommendation from #84, #47, #50, but the problem stills present. I need help.
