warning: not enough free space in mail queue: 38384640 bytes
This last warning looks quite uncomprehensible, message size limit is
50000000, and sure 38384640 is less than 1.5*msl, so what's the problem?

does the system produce any kind of logs at the time problem happens?
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:
