Hi, In this case we have: HugePages_Total: 34104 HugePages_Free: 34104 HugePages_Rsvd: 0 HugePages_Surp: 0 So, I'm not sure if it can be related with 1825814. Also, for people not seeing this issue, how much memory do you have in your baremetal systems? What's the minimum required memory for running an AIO system. Our failing system have 97 GB and free -h shows. total used free shared buff/cache available Mem: 93G 84G 3.2G 66M 5.6G 4.8G Swap: 0B 0B 0B A couple months ago I reported a similar issue[0], in that case after three days in stand-by the system started to throw Out of Memory errors. Does anyone has performed a longevity test for some days? Maybe the working systems might fail after a while if the memory usage keeps increasing over time. -Erich [0] http://lists.starlingx.io/pipermail/starlingx-discuss/2019-February/002923.h...

Memory exhaust happens because so little 4K memory is allocated for system/software load.

The bug where a single CPU was taking all of the workload is resolved. What we observed seems to be an issue with memory exhaust, additional information was gathered an added to this bug for further troubleshooting: https://bugs.launchpad.net/starlingx/+bug/1826308 If additional information is required, please, just let us know.

Can you set up a live debug session so that some container SMEs can investigate?
