the spool directory is inside a custom direcotry: /sonicle/var/spool/mqueue, which is under the root zfs dataset with more than 1TB of free space, and it's always been there for years. Also the binaries are built 32bit with large files, and they also worked like this for years.
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: Transcript of session follows.
