--- Comment #1 from O. Hartmann <ohartmann@walstatt.org> ---
OS: FreeBSD CURRENT (FreeBSD 13.0-CURRENT #168 r368515: Thu Dec 10 15:01:30=
 CET
2020 amd64), port clamav-0.103.0,1 and clamav-unofficial-sigs-7.0.1.

Roughly seven days ago the access to the hosts/netoworks providing clamav's
update files were blockes by our firewall. Since 12th of December, clamscan=
 is
running with two instances for a user (myself) on the specified host and it=
 is
unkillable. I tried almost every KILL signal to stop the process as root, as
the UID it runs as, with no success.

Opening files with vi doesn't work or starting a new screen with screen com=
mand
(sysutils/screen, screen-4.8.0) is stuck forever - the attached tty is
irresponsive, ssh sessions are stuck and stay in that state forever.

The problem looks like a full /tmp or /var/tmp filesystem, but there is ple=
nty
of space left and I can't see anything wrong with out of space or out of
inodes.
