If you choose the default interval, we recommend
you also set the MinQueueAge option (?§24.9.78 on page 1057).
If interval is specified as zero, the effect is the same as though it were omitted. If
interval is negative, the following error is logged and printed and sendmail exits:
Invalid -q value
If interval is nonnumeric (if you specify O when you mean zero), the following error
is logged and printed, and sendmail exits:
Invalid time unit `O??
The process that was given the -qp command-line switchis the controlling process. It
could be the listening daemon (if -bd or -bD were also used), or it could be a queue
processing daemon (if only -qp and other queue processing limiters were specified).
The controlling process has two special properties:
??? To restart the persistent queue runners, you must instead restart the sendmail
controlling process. You do that with a SIGHUP signal (as normal). If you try to
signal the individual persistent queue runners, they will restart but with a penalty
(each can be restarted this way only 10 times; see later in this section).
