everything came back fine including its three analog VGs.

Problem: Name Server (ns3) has crashed Cause: Resource shortage Affects: Multiple services Started: 03/09/2010 07:55 AM Resolved: 03/09/2010 08:50 AM
The server had not crashed, and was still answering name queries (just not all of them). It experienced a resource shortage caused by running out of file handles, which resulted in it not being able to accept every new connection. The root cause of the shortage is unknown. Restarting the name server fixed the problem.
Since there are four name servers at Case, and client name resolution has failover built in, the loss of one name server should have minimal impact.
Network Engineering has been called and is looking into the problem.

A log rotation was silently failing which caused the web server logs to grow beyond acceptable limits, causing the web server to that serves the wiki to crash.
We have manually rotated the logs and restarted the wiki. We will look into why the log rotation was failing and will better instrument the wiki itself so that if it should crash again we will receive more timely notification.

The MyCase portal services were restarted and tested successfully following this morning's database maintenance but then began having trouble about an hour later. Most likely cause is a process that did not stop correctly on restart. A full shutdown and restart of all portal services corrected the problem.
