No light bubble was turned on over my head. Anyone else get clamav to  
run with monit?
Anyway, here is a couple of other things to try.

1) Remove the dependencies and only test the clamav entry

check process clamav-milter with pidfile /var/run/clamav/clamav- 
milter.pid
    start program = "/etc/init.d/clamav-milter start"
    stop  program = "/etc/init.d/clamav-milter stop"
    if failed unix /var/run/clamav/clamav-milter.ctl then restart
    group virus


Does it work now? Errors propagate upwards and it could be a problem  
with the depending files. Probably not though.

2) The only other thing that can go wrong here is reading of the pid  
in the pid file and that getpgid() fails. To get more debug info you  
could replace the function Util_isProcessRunning in util.c with this  
one and recompile monit. Send us the output when you run "monit  
validate"

int Util_isProcessRunning(Service_T s) {
        pid_t  pid;
        ASSERT(s);
        errno= 0;
        if((pid= Util_getPid(s->path))) {
                log("PID: Got pid %d from %s\n", pid, s->path);
                if( (getpgid(pid) > -1) || (errno == EPERM) ) {
                        log("PID: OK\n");
                        return pid;
                }
                log("PID: Error -- %s\n", STRERROR);
        } else
                log("PID: No pid found at %s\n", s->path);
        Util_resetInfo(s);
        return FALSE;
}

Alternatively you could run gdb on the monit executable as shown  
below to the same effect.
