This was a OOM caused by the backfill.

From 30.dmesg.txt

[Wed Nov 20 08:16:29 2024] oom-kill:constraint=CONSTRAINT_MEMCG,nodemask=(null),cpuset=cockroach-system.service,mems_allowed=0,oom_memcg=/system.slice/cockroach-system.service,task_memcg=/system.slice/cockroach-system.service,task=cockroach,pid=
16163,uid=1000
[Wed Nov 20 08:16:29 2024] Memory cgroup out of memory: Killed process 16163 (cockroach) total-vm:40695620kB, anon-rss:31048468kB, file-rss:67328kB, shmem-rss:0kB, UID:1000 pgtables:65408kB oom_score_adj:0

I'll see if I can track down where all the memory was, but we already have a tracking issue #133114.

The configuration for this test is:

2024/11/20 08:12:26 framework.go:556: test variations are: seed: -5951460172509227715, fillDuration: 10m0s, maxBlockBytes: 1024, perturbationDuration: 30m0s, validationDuration: 5m0s, ratioOfMax: 0.500000, splits: 1, numNodes: 30, numWorkloadNodes: 2, vcpu: 32, disks: 2, memory: low, leaseType: expiration, cloud: gce, acMode: fullNormalElasticRepl, perturbation: {}

Previously this test was setting the memory spec before it called randomize. This could set it back to low memory. We already know that low memory configuration doesn't work for backfill as part of #133114.

This change calls randomize and then sets the memory configuration.

Epic: none
Fixes: #135799

Release note: None
