           Summary: Server crashes periodically after upgrading to
                    11.1-RELEASE-p9
           Product: Base System
           Version: 11.1-RELEASE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: kern

          Reporter: samorders at gmail.com

Server has been crashing every 2 or 3 days since upgrading to 11.1-RELEASE-p9.
Downgraded to 11.1-RELEASE-p8 and all was well, went back to -p9 and it started
crashing again.

I posted on the forums and was asked to post a bug report.
