Do you also get this log entry?

postfix/scache[21161]: fatal: event_loop: select: Bad file descriptor

The scache process then exits and the server side can't talk to it any more.

I also got (earlier) a few

postfix/scache[21161]: warning: scache_multi_drop_endp: close(0): Bad file descriptor

Looks more like a bug in postfix to me... [still investigating]
This is probably worth a pkg PR.
