Hello,
I have a system running for some years, recently started to send "452 4.3.1
Insufficient system storage" errors randomly.
Sometimes 2-3 during the night, sometimes many more (20-30).
Postfix is running under an illumos zone, over a zfs data pool with more than
1TB of free space.
Size of emails with error is small enough to fit max message size.
The error email shows this:
