Over the last several days, the web servers mercy and smile have been unstable due to a kernel panic caused by a bug in the OS kernel, triggered by some heavy usage. A workaround has been identified – using a different OS for the NFS server. This workaround has now been tested and the old architecture has been restored, with all of the NFS mount points being served from a single machine. The last downtime to handle this problem, and switch over to the new NFS server occurred this morning at 6:25 AM CDT, lasting until 6:45 AM CDT. We apologize fir the disruption in service.
