After an IP-change, all of our crons are not executed, although DA says (in the cron log) they are. We heard there was a tool for it, but I havent been able to find it. If anyone's got a hint or advice...
What cronjobs aren't being executed? DA-based cronjobs, or all system cronjobs?
The only reason I can think of for cronjobs to not run after an IP# change would be for DA-based cronjobs, if DA was not updated for the new IP#.
If you've changed your main IP# and haven't contacted DA sales yet to have your license updated you should do so as soon as possible; lots of things stop working until you do.
