Spurious warning about core file size

2022-04-22 15:06:53 0 [Warning] setrlimit could not change the size of core files to 'infinity';  We may not be able to generate a core file on signals

Is shown even when core file size is already set to 'unlimited'

$ ulimit -a | head -n1

core file size          (blocks, -c) unlimited

This may lead to users attempting to tune something which is set correctly already.

Likely present in all versions. Propose to fix in 10.7.

May also be good to change 'infinity' to 'unlimited' in messages (or possibly this is the cause of the issue).
