some way to configure container to report smaller memory size Not in the usual, expected way. Perhaps by having 7z call docker-specific commands. However I do not know which commands, from inside a container.

-mmt2 switch will help you. OK. Thanks. We'll use that option. What changed? Switched from ubuntu22 to ubuntu24. Here is the previous configuration. free -h total used free shared buff/cache available Mem: 68Gi 17Gi 2.4Gi 117Mi 48Gi 49Gi Swap: 0B 0B 0B 7z 7-Zip [64] 16.02 : Copyright (c) 1999-2016 Igor Pavlov : 2016-05-21 p7zip Version 16.02 (locale=en_US.UTF-8,Utf16=on,HugeFiles=on,64 bits,36 CPUs Intel(R) Xeon(R) Platinum 8124M CPU @ 3.00GHz (50654),ASM,AES-NI) 7z b 7-Zip [64] 16.02 : Copyright...

The container has restricted memory and cpu. However linux diagnostics may show the information from the host OS, not the container, so it's misleading and could be the source of the problem. free -h total used free shared buff/cache available Mem: 68Gi 17Gi 2.0Gi 66Mi 49Gi 50Gi Swap: 0B 0B 0B 7z 7-Zip 23.01 (x64) : Copyright (c) 1999-2023 Igor Pavlov : 2023-06-20 64-bit locale=en_US.UTF-8 Threads:36 OPEN_MAX:65536 7z b ~~~ 7-Zip 23.01 (x64) : Copyright (c) 1999-2023 Igor Pavlov : 2023-06-20 64-bit...

The CI jobs run in a docker container. Both memory and CPU will vary depending on where the container is run. The output above showed my local computer, but the important thing is CircleCI which could be different. We reverted back to ubuntu 22.04. In the near future I will try -mmt2 or -mmt4 as you suggest.
