Dale,

   I agree that there is no apparent simple answer. Unless the ENOTTY error
relates to mailing the output rather than displaying it, that error is
likely not significant. Examples:

ioctl(3, SNDCTL_TMR_TIMEBASE or SNDRV_TIMER_IOCTL_NEXT_DEVICE or TCGETS,
0xbfac8de8) = -1 ENOTTY (Inappropriate ioctl for device)
stat64("/var/cache/logwatch/logwatch.CSbhPkjD/none", 0x9ef6180) = -1 ENOENT
(No such file or directory)
stat64("/etc/logwatch/scripts/services/zz-zfs", 0x9ef6180) = -1 ENOENT (No
such file or directory)
ioctl(3, SNDCTL_TMR_TIMEBASE or SNDRV_TIMER_IOCTL_NEXT_DEVICE or TCGETS,
0xbfac8de8) = -1 ENOTTY (Inappropriate ioctl for device)

Thanks,

Rich
