I've heard several stories about system problems if there is insufficient swap space; and now it begins to sound like the mysterious error that crops up with uucp running is also swap related. It sounds like 3B1 UNIX does not properly detect the end of the swap device; most likely, it detects the out-of-swap-space error, because it apparently kills processes, but likely has a boundary value problem and is overrunning the end of some table related to swap. (That's a bug I've seen in many UNIXes). Seems to me like there are two things that need to be done: (1) find a way to increase swap space (I've half a hope of running GNU Emacs on this machine, and will need much more than the default 2.5M of swap), and (2) locate the garbage planter on swap errors. I've not received my machine yet, so am stuck. A friend of mine who was a longtime 7300 user remembers that an early version of the UNIX allowed swap size specification. Does anyone have such a disk around, to disassemble? [I can't wait to get my machine. Is anybody interested in putting up a decent UNIX on it?] Andy "Krazy" Glew. Gould CSD-Urbana.
