Looks like the old routing-related problem to me; a huge count for network
allocations, plus a system that has lots of route changes (whenever diald
starts or stops my net connection, which is fairly often).
System:
Linux khms.westfalen.de 2.0.33 #7 Thu Dec 25 15:16:41 CET 1997 i486 unknown
Unmodified kernel sources from ftp.kernel.org.
This is an empty system (X with no login, some console bash sesseions, the
usual daemons, _nothing_ else - even killed top), after 2.5 days uptime,
practically unuseable:
total used free shared buffers cached
Mem: 62676 54212 8464 2584 912 1608
-/+ buffers/cache: 51692 10984
Swap: 229748 13372 216376
This is essentially the same system (less bash, more login) fresh after
reboot:
total used free shared buffers cached
Mem: 62676 31940 30736 31168 5444 11160
-/+ buffers/cache: 15336 47340
Swap: 229748 0 229748
Something is eating memory like there is no tomorrow. That's around 50 MB
gone missing from my 64 MB!
Shift-ScrollLock shortly during reboot:
