Add cgroup v1 compat patch for OpenJDK detection (6.18.38-1gl1)#322
Merged
Conversation
Reverts upstream commit af000ce85293 ("cgroup: Do not report
unavailable v1 controllers in /proc/cgroups") adapted for 6.18.
With CONFIG_CPUSETS_V1 and CONFIG_MEMCG_V1 disabled, cpuset and
memory controllers disappear from /proc/cgroups. OpenJDK 11-24
relies on /proc/cgroups to detect cgroup memory/CPU limits — without
them the JVM defers GC and triggers OOM in containers.

Summary
af000ce85293("cgroup: Do not report unavailable v1 controllers in /proc/cgroups"), adapted for the 6.18 kernelProblem
With
CONFIG_CPUSETS_V1andCONFIG_MEMCG_V1disabled (upstream default in 6.18), thecpusetandmemorycontrollers disappear from/proc/cgroups. OpenJDK 11–24 relies on/proc/cgroups(v1 API) to detect cgroup memory/CPU limits — without them the JVM defers GC and can trigger OOM in containers despite not needing all allocated memory.References
