[mrtg] I think I found the problem

Problem was that someone changed IPs on some big routers without telling me,
so they were not being found.
Anyway, is there a reason why MRTG is doing 25 retries per interface at 2
seconds each?? When a core router goes down with a hundred interfaces, MRTG
will run forever..... Take a look at these errors I got from just one down
router when running MRTG from the command line.
It waited two whole minutes for that one router.
I thought its supposed to do 5 retries only?

Thanks
