Apple has a pretty good article that goes into more detail on these:</div><div><br></div><div> <a href="http://support.apple.com/kb/HT1392">http://support.apple.com/kb/HT1392</a></div><div><br></div><div>To figure out what's causing the problem, you need to check the kernel panic logs. On 10.6 they're located in
in /Library/Logs/DiagnosticReports, while in 10.2 - 10.5, they're
located in /Library/Logs/PanicReporter. If there's a specific application that's causing the problem, you might try uninstalling it to see if the problem goes away. If that doesn't work, I'd begin going through Apple's "Isolating issues in Mac OS X" process, documented here:</div><div><br></div><div> <a href="http://support.apple.com/kb/TS1388">http://support.apple.com/kb/TS1388</a></div><div><br></div><div>Sometimes, it's as simple as re-installing a third-party application, while in the worst case, you might need to reinstall the OS.</div><div><br></div><div>Hope that helps.</div><div><br></div><div>-<span class="Apple-style-span" style="font-size: 12px; ">-Patrick</span></div><div><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: medium; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: medium; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: medium; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div><br>----------------------------------------------------------------------------<br>Patrick McNeal<br>Macintosh Platform Coordinator<br>ISDA, Information Services and Technology<br>Massachusetts Institute of Technology<br></div></div></span></div></span></div></span></span></div></body></html>
