Network outage CITRIS May 31 between 4:30pm to 6:00pm

by

The citris 8810 switch with Black Diamond chassis incurred an MSM failover on May 29 around 12:51PM.

It appears that the MSM failed over due to a process crash. The process that crashed was snmpmaster process. It appears that the backup MSM was not in synch with the master which would have caused an outage as the hitless failover could not take place if the backup MSM was not in synch.

I plan to take some actions to prevent this happening again around on May 31 around 4:30pm-6:00pm . Also the firmware upgrade will be applied as well. The switch may require to reboot and it should take less than 10 mins during that time you might experience the intermittent issue. The extra time is scheduled for if there is an unexpected occurrence.

During this time, the server will be upgraded to the latest version of [Openfire](http://www.igniterealtime.org/projects/openfire/index.jsp) (version 3.7.0). This version [contains numerous bug fixes](http://www.igniterealtime.org/builds/openfire/docs/latest/changelog.html) which should increase the reliability of the service. In particular, there are a couple memory leak fixes that might solve a problem we have been having with our server running out of memory.
