Hello, *Background :* I am working on a small cluster that is managed by Base Command Manager v10.0 using Slurm 23.02.7 with Ubuntu 22.04.2. I have a small testing script that simply consumes memory and processors. I run my test script, it consumes more memory than allocated by Slurm and as expected it gets killed by OOM killer. In /var/log/slurmd, I see entries like : [2024-05-29T08:53:04.975] Launching batch job 65 for UID 1001 [2024-05-29T08:53:05.016] [65.batch] task/cgroup: _memcg_initialize: job: alloc=10868MB mem.limit=10868MB memsw.limit=10868MB job_swappiness=1 [2024-05-29T08:53:05.016] [65.batch] task/cgroup: _memcg_initialize: step: alloc=10868MB mem.limit=10868MB memsw.limit=10868MB job_swappiness=1 [2024-05-29T08:53:19.530] [65.batch] task/cgroup: task_cgroup_memory_check_oom: StepId=65.batch hit memory+swap limit at least once during execution. This may or may not result in some failure. [2024-05-29T08:53:19.563] [65.batch] done with job Inspecting with sacct, I see : $ sacct -j 65 --format="jobid,jobname,state,exitcode" JobID JobName State ExitCode ------------ ---------- ---------- -------- 65 wrap FAILED 9:0 65.batch batch FAILED 9:0 Based on my previous experience with a RHEL based Slurm cluster, I would expect the state to be listed as OUT_OF_MEMORY and the exitcode to be 0:125. *Question : * 1. How do I configure [slurm,cgroup].conf such that when Slurm kills a job due to exceeding the allocated memory, sacct reports the state as OUT_OF_MEMORY?
