My Web server was up 121 days before a power outage knocked it down, that is pretty good given that the site record is (I believe) 135 days for a SunOS 4.1 box. In my opinion my news server isn't as stable. I see about 1-2 week uptimes. Since I've installed ccd and increased my alt.binaries partition size, I am no longer running out of disk space on a regular basis and I haven't seen that pesky "panic: free vnode isn't" message lately. Again, that is not a guarantee that there's a relationship, but there is an apparent correlation. ...
