Description emmacdon 2021-04-20 16:09:29 UTC
Created attachment 1773820 [details]
First memory climb spotted, excluding most recent jump

Description of problem:

Created 1000 unique cluster deployments and installenvs using assisted service. After successfully generating the ISOs, I left the cluster over the weekend (2021-04-17 and 2021-04-18) untouched. When viewing the cluster again (on the following Monday, 2021-04-19), the memory usage had climbed much higher during the time I was not using it over the weekend. It climbed to 4Gib usage and continuously used that much through Monday (2021-04-19). There was another memory jump, again while the cluster was not in use, overnight (2021-04-19 to 2021-04-20), resulting in a continuous 5Gib usage currently (2021-04-20 16:08:00).


How reproducible: 

Enable observability and load assisted-service on a cluster, generate 1000 cluster deployments and installenv, (make sure 1000 ISOs were generated), leave cluster alone for a couple of days and observe.

Need to focus on cloud use case.

Comment 3 Hao Liu 2021-05-05 17:29:38 UTC
verified in v1.0.19.3 of assisted installer that the memory leak is no longer being observed. monitored over 16 hr

Comment 5 bjacot 2021-06-17 19:51:04 UTC
moving to verified since Hao said he verified it.
