34 <PRE>I think the cron job idea is the best I've seen out of all of this. It uses
35 the least amount of resources, has less overhead, and no database issues. A
36 cron job that runs every
5 minutes would work great for that. All you would
37 have to do is write a script that checks to see if services is running, and
38 if it finds it isn't, start them up.
40 One feature I'd like to see though that the cron job idea could benefit from
41 is being able to send the process arguments and it work to where you can
42 send a global from outside of the ircd. I could see this being useful for
43 the script to send a global to all users with a warning to identify to
44 nickserv and an apology about services being down. I could see other
45 benefits from this as well later on down the line in conjuction with logs
46 and tail -f if one didn't care to log into irc.
