Note that the two words in the subject should NOT go together. ;) We have a rather large problem with NIS. Our mail server is a slave NIS server, and at some random times when there's more than a few sendmail processes running, it'll dead peg ypserv on CPU. And then, sometimes when it does THAT, ypserv will wig out totally, stop handling and requests, eat 100% CPU time, and refuse to restart after we kill it. That should not be; I'm watching sendmail in another window, and we're talking about ~20 sendmail processes, on a Pentium Pro with SCSI drives. It shouldn't be working half as hard as it is, and certainly shouldn't be dying on us. Is this a known problem, or some interaction between sendmail and ypserv that I'm not aware of? I have sendmail's resource limits cranked down way low now, I run the queue manually every so often (that spawns a lot of processes and kills the machine right quick), and I have top running constantly in a window on the corner of my screen so I can kill sendmail when it gets pegged quickly. But I'd kinda like to resolve this so I could get some sleep, and not have to worry about our mail server dying under what is really a pretty small mail load.
