sorry bout this one people but im out of ideas. I cant see why i get so many underruns?

I have the buffer at 40 and pre post etc to 1 I assume it means it cant write them all to disk but im not sure on this any obvious pointers pleasE?

If you are getting this many constantly it normally implies your machine is really busy and just can't keep up. If you get them in burst its sometimes means that something just hogs all the cpu for a few seconds. My slimserver does that on my box a few times a day.
