Note that we can already answer that from the dmesg output: [9501543.900845] Memory cgroup out of memory: Kill process 22465 (perkeepd) score 530 or sacrifice child [9501543.901793] Killed process 22465 (perkeepd) total-vm:1648956kB, anon-rss:1062200kB, file-rss:0kB, shmem-rss:0kB The fact that it says "Memory cgroup out of memory" not "Out of memory" at the beginning indeed means it's a cgroup limit. We can also see that it was using about 1GB of residual memory, so it's reasonable to assume the cgroup has a memory limit of greater than 1GB. That's not enough to answer whether this is a memory leak or not though. 1GiB seems like a lot of memory for perkeep, but it also might be okay for some workloads, so without information about what that memory's being used for, we can't be sure whether anything's really wrong or not.
