Additional information
- OS distribution and version Mac Monterey 12.1, Redis version: Redis 7.0rc2
- Steps to reproduce
a. launch the Redis process with nobody,
sudo -u nobody src/redis-serverb. set the rdb file to readonly, for examplechmod 0444 dump.rdbc. sendshutdowncommand to the server, the server will crash directly
