@lanodan but since fluentd was tailing the logs, the only effect of it not keeping up should be that a log file gets rotated before fluentd is done with it.
Unless...
Unless it kept the old logfile open which resulted in there being no space for the new logfile to grow.
But I'd thin more stuff would break in that case... and I didn't see a "node out of disk" alert.
So it must've been containerd not keeping up with copying from a pipe to a file?
