Possible bug: ftp disabled after SIGHUP? (squid-1.NOVM.19)

Hi!

FTP seems to always get disabled when I -USR1 my cache.. and for some
strange reason the cache also thinks it is being -HUP'ed.

And where is that HUP coming from? Am I doing that, or is squid doing that
or after the USR1 or what? I'm not sending any HUPs in crontab or anywhere
else.. (unless squidtimes or calamaris.pl HUP the cache, do they?)

And I don't see why that would matter - FTP shouldn't be disabled just
because Squid gets a HUP right after an USR1 ..

A sample of cache.log:

Any suggestions would be welcome.. for example, would it be a good idea to
raise the number '2' to something higher, like say, '20' in the following
code stub? Or just disable the disabling entirely?

ftp.c:
------
ftpServerClosed(int fd, void *nodata)
{
    static time_t last_restart = 0;
    comm_close(fd);
    if (squid_curtime - last_restart < 2) {
                                       ^-------------------- here!
            debug(9, 0, "ftpget server failing too rapidly\n");
        debug(9, 0, "WARNING: FTP access is disabled!\n");
        ftpget_server_write = -1;
        ftpget_server_read = -1;
        return;
    }
    last_restart = squid_curtime;
    debug(9, 1, "Restarting ftpget server...\n");
    ftpInitialize();
}

Please reply directly, as I'm not subscribed to the Squid mailing lists.
