I have strange problem with heavly loaded machine (486 DX4, 40 MB RAM, 260 MB
Swap) running FreeBSD 2.2.8-STABLE.
Average once per two weeks, one or a few procceses (usually w, uptime or top,
sometimes qmail or shell) dies with ``Can't allocate memory'' message.
Probably that's not a hardware problem (I've obserwed this behavior on other
my servers).
Can you help me with it?
