sysctl.d/50-default.conf in aaa_base has new defaults: Remove kernel.pid_max limit (bsc#1219038) kernel.pid_max is one of multiple mechanisms to restrict number of processes [1]. Its kernel default is scaled with nr_cpus but 1024 tasks/cpu cap is too much if they were all running and it is also too little when they are idle (memory being bottleneck). Bump the limit to maximum kernel-accepted value and defer to other mechanisms for tasks limit enforcing. (This way we converge to same config like upstream systemd [2] but we ship distro defaults together from this package.)
