RAL Tier1 Operations Report for 17th December 2018
Review of Issues during the week 10th December to the 17th December 2018. |
- Docker containers were updated with latest version of singularity to patch against CVE-2018-19295
- Previous weeks have seen a large number of gridFTP errors into Echo with: "Address already in use’”. We found NIS was using a large number of ports (> 10000) on all external gateways. We disabled this on Monday and the errors have gone.
- There have been issues with the Tier-1 Tape robot. One handbot and one tape drive is broken. On Friday 14th an Oracle engineer attended site to fix the problems. He discovered another minor issue which will probably be fixed next year now.
- Change freeze now in place - Only change required for critical security patching or major incident will be implemented until the new year.
