Virus scanner lock file not removed

[David Osborne]

On our systems with MailScanner & Sophos, the sophos-autoupdate script
creates /tmp/SophosBusy.lock but the file is never removed, preventing
MailScanner from running. If I remove the file manually, everything is
OK until the next hourly check. What's wrong with our installation?

We're using MailScanner 4-12-2 (installed from RPM), Sophos, Exim 3.36,
running on RedHat 8.0
