I'll try to see how few shares cause the problem... I've been running with 4 nfs shares (reorganized the shares to group a lot of them into 1) and things are great.

SteveT Steve Litt* http://www.troubleshooters.com/ Troubleshooting Training * Human Performance Thanks for the suggestion Steve, but the problem with virtuoso was resolved a while back. I've been getting the slowdown/freeze even when virtuoso isn't showing up on the cpu or i/o charts. It's possible/probable that there are other problems with KDE but I like KDE more than the other desktops and would prefer to resolve the issue rather than abandon the desktop. The issue remains that something is going on that doesn't show up on top or iotop that is causing a serious periodic slowdown. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
