Public bug reported:
Tested with rabbitmq-server 3.8.2-0ubuntu1.1 (focal)
The postrotate script (`/etc/init.d/rabbitmq-server rotate-logs`) also invokes
a log rotation, which conflicts with logrotate itself.
It was working as expected on Xenial, but it became a problem on Focal and
RabbitMQ 3.8 (see the tests below).
Hence, these lines should be removed from the logrotate config:
sharedscripts
postrotate
/etc/init.d/rabbitmq-server rotate-logs > /dev/null
endscript
It seems the daemon detects itself the log rotation, no postrotate
command needed.
Tested with Vagrant (VirtualBox) and a fresh install on each run.
Clock syncing needs to be disabled with:
v.customize ["setextradata", :id,
"VBoxInternal/Devices/VMMDev/0/Config/GetHostTimeDisabled", "1"]
Test #1, current config (not expected, double log rotation)
