My box suddenly slowed down, so I checked with TOP and a program called<br>
md2_raid1 is sucking 20% of the cpu cycles -- and making it difficult to even<br>
type this email. :( This box is running FC11<br>

Next stop was the log file and this is at the end of /var/log/messages:<br>

<br>
Does the OS suspect a problem with one of both of the hard drives?<br>
<br>
Turned the box off last night so the uptime is less than 2 hours.<br>
<br>
Another program, npviewer, also has been stealing cycles and I killed that<br>
first, hoping that the box would return to normal. Didn't help much.<br>
Checking in the log I see this line:<br>
<br>
Dec 13 10:41:42 Sarge kernel: npviewer.bin[2584]: segfault at ff99cd48 ip<br>
ff99cd48 sp bfb6773c error 14<br>
<br>
and I have no idea what it is trying to tell me. Note that this was about<br>
an hour before the box started checking the raid array.<br>
<br>
Hints would be appreciated.<br>
