issue with /tmp

[David Mehler]

Hello,

Running FreeBSD 11.1 and imapsync it failed while writing to /tmp. I
then tried to use vi to open a file, got the below error:

#vi 10-mail.conf

/tmp: create/symlink failed, no inodes free
ex/vi: Error: /var/tmp/vi.recover/: No space left on device
ex/vi: Modifications not recoverable if the session fails
ex/vi: Error: 10-mail.conf: No space left on device
ex/vi: Error: Unable to create temporary file: No space left on device
