Should the limit be simply raised? The 256M setup is crumbling on
several fronts (runtime tests, modernisation of X, various non-x86
qemu targets). Adding per-image/target exceptions, custom
non-upstreamable patches, or sticking to deprecated configurations
isn't the right thing to do, I think.
The modification of set default RLIMIT_NOFILE(4k) just keeps sync with
the one in sysvinit,
if the fronts you mentioned are working fine on sysvinit, I think it
should be OK on systemd
but whether it has side effect or not still depends on the result of
image test
The fix is trying to fix the blocking issue while switching init manager
from sysvinit to systemd for poky
Hi RP,
Should we make HIGH_RLIMIT_NOFILE configurable from local.conf?
Then we could modify it according to the requirement, such as set it to
4k at image test

The rpc.statd allocates memory according to RLIMIT_NOFILE,
so decrease it to 4k to keep sync with sysvinit
After applying the patch, the memory cost is the same with sysvinit
