May be, sombody can give us advise on the following panic. This is
on our proxy server: P-II 266, 128M RAM, ASUS P2L97, Intel 440LX chipset,
"almost" 2.2.5 (2.2.5 with kernel and lkm's from STABLE some two
days after 2.2.5 released). Quite busy -- squid getting about 50000
requests per hour at load peaks.
May be I'm missing something and simply need to reconfigure kernel
in some way?
