Hi!
One of my production machines (3.8-stable) has suddenly started panicing
every couple of hours. I found out that the culprit is smbd, eating through
memory like there's no tomorrow (approx. 10Mb / minute! ). Can't figure out
what has triggered it, nothing changed on the machine lately and there is
only one active w2k client, writing a 2.5kB file every 15 seconds or so. I'd
be glad of any assistance, even pointing out any stupid mistakes I have
made, because this is driving me nuts.
