On hirsute, on Jan 20, postfix stopped sending outgoing mails with the error
Feb 22 23:35:18 pccross postfix/smtp[9582]: fatal: unknown service: smtp/tcp
There were no changes in the system other than daily upgrades.
Strace shows that `smtp` process (while chrooted), after successful open of the file in the queue, tried to use NSS, ran `fstat()` against `/etc/nsswitch.conf`, that succeeded (presumably using the copy in the /var/spool/postfix/etc/ directory), but did there was no subsequent read, and the next syscall is `sendto()` of the error message to syslog.
There was a big upgrade between the last successful and the first unsuccessful email delivery, and among other things libc was updated from 2.32-0ubuntu6 to 2.33-0ubuntu2. I suspect that there was some change in the NSS in libc that resulted in the failure of `getservbyname()`.
Is anybody else observing this problem?
