[clamav-users] Clamd Socket Occupied

[Colony.three]

As Red Hat hasn't solved the problem of unix:sockets, I had to make my own systemd files.  But there's a little problem.

clamd.socket
==========================================================
[Unit]
Description=Socket for Clam AntiVirus userspace daemon
Documentation=man:clamd(8) man:clamd.conf(5) http://www.clamav.net/lang/en/doc/

[Socket]
ListenStream=/run/clamav/clamd.sock
#ListenStream=127.0.0.1:1024
SocketUser=clamilt
SocketGroup=clamilt
RemoveOnStop=True

[Install]
WantedBy=sockets.target
==========================================================

clamd.service
==========================================================
[Unit]
Description = clamd scanner daemon
After = syslog.target nss-lookup.target network.target
Requires=clamd.socket

[Service]
Type=forking
ExecStart = /usr/sbin/clamd -c /etc/clamd.d/scan.conf --foreground=no
Nice = 5
Restart = on-failure
PrivateTmp = true

[Install]
WantedBy=multi-user.target
Also=clamd.socket
==========================================================

Now I find that after enabling/starting clamd.socket, clamd.service is not starting.  And in /var/log/maillog is:

Huh?  It's in use by its own .socket.  The .socket runs fine, and when I stop it /run/clamav/clamd.sock goes away like it should.  Permissions are fine, and selinux is Permissive.

Any ideas?
