> https://bugs.openjdk.java.net/browse/JDK-8266490
> extended the OSContainer API in order to also support the pids controller of cgroups. However only pids.max output was added with 8266490.
> There is a second parameter pids.current , see https://www.kernel.org/doc/html/latest/admin-guide/cgroup-v2.html#pid
> that would be helpful too and can be added to the OSContainer API .
> pids.current :
> A read-only single value file which exists on all cgroups.
> The number of processes currently in the cgroup and its descendants.
> Best regards, Matthias
