Sometime during the weekend, the ftp server on www2 decided that its license had expired. Until a new license could be obtained, the standard ftp server (wu-ftpd) was run. This led to some slow response (wu-ftpd operates under the xinetd master daemon) for much of the day. The vendor provided a new license key at 4:30 PM. This was installed, and ftp service was restored to normal.
The secondary web server www2 became unresponsive when the SurgeFTP service began consuming 99% of the CPU cycles. We were unable to stop the service or gracefully restart the system. The system was powered down, then back on, after which the system ran normally.
Merlin2 became unresponsive to fileshare access today at 5:30 PM. The console was still responding, and we were able to log on. Access to the disk arrays appeared to be impaired – we were unable to list the disks or view their contents. No pertinent events were logged in the Event Log. The system was rebooted, and was back to normal.
We have made an adjustment to the antivirus software (changed vendors), and will keep monitoring.
The movement of files from the old Merlin2 server was completed successfully. The new server is ready and available.
Data from the Administrative file server Merlin2 will be moved to a new server in an effort to solve the recent instability problems. Merlin2 will be unavailable from 5:30 PM until midnight Friday, May 19th, 2006.
ALEXANDRIA activated its spare memory bank on 11 April. Since that time it has not frozen. A new server is en route to replace the defective replacement server.
