Inoculate scanner gets skipped after a while as if its marked busy

[Julian Field]

Sounds to me as if the virus updates are hanging, which would lock out the
virus scanner. If you don't want to use update_virus_scanners, but are
still using inoculate-autoupdate then make sure you are calling it
correctly (you have to add the inoculate installation directory on the
command line, you can get the correct directory from
/etc/MailScanner/virus.scanners.conf).

This is the usual cause of these problems. Either that, or is there a
chance that inoculate is waiting for keyboard input?
