- Did you change anything major to do with memory management or process
- scheduling between 0.98 pl1 and pl6?
-
- I did the jump a couple weeks ago, skipping everything in between, and after
- recompiling stuff left and right to get rid of the stat() warnings :-)
- things seemed to be going well.
-
- However, on occasion (and seemingly more frequently) the machine will just
- slow down to a crawl to the point that hitting CR at the shell prompt takes 20
- minutes to respond ... until about a dozen "out of memory" messages appear, a
- few processes get killed off, and then it's back to normal.
-
- I never saw this phenomenon running under any previous releases, except
- when I did things like "make -j" on a big package. :-) But it didn't even
- take much to cause it in pl6 -- a few shells, a couple editors, and some
- news thing (rn or news spooling in the background...). And I'm back on pl1
- now running the same binaries with no trouble, so it seems likely that
- something weird is going on in the kernel, rather than a true memory
- shortage.
-
- I have 8 MB of memory, but no swapping installed. (never needed it before)
