Yesterday I compiled the complete mit X11R5 stuff in about 2.5 hours on my 386BSD system at home ! That must be some more stuff than just the kernel of 386BSD. I guess your RAM is too small or something along that line. [ some text describing similar problem deleted - NB.] >the same thing happens again with a different file.

Re-booting restores the memory >(or swap space?) and allows more compiling to happen until the memory >(or swap space?) fills up again.

If this is >a known problem with a fix, I would be curious to know what it is. I am using 16 MB RAM and don't have this problem. Perhaps you are right that memory is allocated but not free'd or something similar. Oh, I even didn't "fix" (is it really a bug ?) make. Sorry, that I can't help other than saying "it doesn't happen to me" even if I compile a large amount of code like X11R5.
