Could this be a one time flu= ke and I > shouldn=92t worry about it? I had to research this earlier this year. The default is 200, so in my case, raising the value to 250 solved the problem. I fixed it by adding the setting to my kernel config and building a new kernel. I believe you can also set it in loader.conf I haven't tried setting it higher than 250 (haven't had the need) but I've seen some posts suggesting that setting it too high can cause kernel panics. I recommend bumping it to 250, then go to 300 if the problem doesn't go away -- but in any event, don't increase it drastically. --=20 Bill Moran http://www.potentialtech.com
