You're running out of processes per child. Try rebuilding your kernel with the following options: options CHILD_MAX=128 options OPEN_MAX=128 You might try just rebooting too. I'd have to see a ps -ax to get a sense of what's going on. hylafax may be leaking memory or file descriptors. > The kernel is compiled with "maxusers" as 40 giving me 656 processes. That is somewhat loose; the above variables control this much more directly. Hm, there was one zombie process. You might want to keep track of those and make sure they don't get too numerous. A zombie process is one that's waiting for it's parent to recognize that it's dead. If big apps (like faxmail or anything fax related) is getting stuck, it doesn't release it's resources until it's postiviely dead. They're generally caused by programing errors related to not understanding the BSD process model.
