On the archives on mailling lists I found nothing interresting (I mean, only the same question but no response) Please help me. It's on a Cobalt Raq4, 512 Mb RAM, kernel 2.2.16C27_III The machine write theses lines for a week, but the system doesn't work like usual (It's very slow). Thanks for any advice.
