March 23, 2015: BBLearn Stability Issue

At 11:28 AM, one of our application nodes (bbapp3a) reporting abnormally heavy CPU use by the WIRIS Math Image Editor service. We took the node out of service to restart it, and had it back online by 11:49 AM.

The Math Image Editor feature will have been unavailable during this window.

When a single node goes out of service, users will automatically be routed to other nodes.

This service has experienced multiple stability issues in the past month; DLT is working with vendor support to investigate the issue.
