Now it was true I forgot to re-instate the mem=512M line for loadlin,
but even so:
/usr/bin/free:
             total       used       free     shared    buffers     cached
Mem:         63740      56064       7676      22160      23032      17396
-/+ buffers/cache:      15636      48104
Swap:       530104        304     529800

should be enough to run slrnpull and expire a newsspool with about
2,000,000 files, right?

Most messages I was able to dig up about this mentioned 2.2.17 and
suggested upgrading to 2.2.18pre. I didn't think there is anything
changed between 2.2.18pre25 and 2.2.18pre26(2.2.18 to be) in VM
handling, so the problem still seems to persist. What are the
suggestions? Moving to 2.4 is not possible, since the isdn compression
module isdn_lzscomp.o won't work in 2.4.

Greetings,
Jurriaan

You could try out my patch that "reserves" virtual memory for root, so
you should be able to login/ssh and clean up if your "faulty" or
memory hungry daemons aren't run by root -- it works fine for me
and I didn't get negative feedback so far:

Andrea Arcangeli's VM global patch got good feedback and according to
Alan Cox it's a potential candidate for 2.2.19,

Good luck,
