That's kind of an odd amount. :) I'll assume you typo'd in a 0 and what you actually meant was 8MB, in which case this machine is woefully underconfigured for what you're trying to do with it. I wouldn't be surprised if the PTY allocation failures happened for other reasons if you're really trying to do this much in 8MB of memory. Memory is very cheap, and even just doubling this poor machine's memory would make a big difference. I'd be more inclined to stick at least 32MB in it and leave myself some room for overhead. Second, if this is a PTY exhaustion problem then it's fairly simple to test, and you should probably do this before you go chasing any wild geese. Just write a little C program to gobble up all the ptys and then print when it's not able to open any more. Shut down the system to single user mode and run it and you'll quickly find out if it's a PTY allocation problem or what, exactly. I don't remember what the PTY constraints in 2.1.5 were - that's all ancient history to me now. :-) I've also forwarded your question to questions@freebsd.org. -- - Jordan Hubbard FreeBSD core team / Walnut Creek CDROM.
