Multi-service Interruption - ECE Virtualization Platform – Memory Failure (Apr 25th 2014)
This issue was resolved at ~4pm on April 25, 2014.
In the morning of April 25th, ECE’s server virtualization platform experienced a hardware memory failure, destabilizing several dependent virtual servers. Faculty, researchers, students and staff experienced the following issues as a result:
- Individuals with MATLAB installations depending on ECE’s departmental licensing server could not use MATLAB
- ECE’s E-mail system experienced numerous LDAP lookup query failures, despite in-place LDAP load-balancing and redundancy. The mail system subsequently failed to deliver messages to @ece.ubc.ca mail accounts. Messages remained queued, but not delivered for 3+ hours.
- The Electric Power & Energy Systems Lab software license server intermittently failed to issue licenses to requesting hosts
The virtualization platform was restored to working order ~4pm on April 25, 2014. All dependent virtual machines and their hosted services were recovered to working order. The issues above were resolved as a result, with e-mail messages delivered up to 3-hours late.
