ok.
tell me, then
When having an http-server-of-choice (tried several), I start downloading
10-50 files at 4Mbps. After some time, the server OOMs. The only processes
running are syslog, nfs daemons (idle) and the web server. This happens
without swap or with swap (1gig swap - fills up, and the server dies).
My last thread about it was "[BUG] 2.4 VM sucks. Again". After a rather
experimental patch my akpm, the problem was solved.
