I'm confused about the meaning of the maximum locked-in-memory address space given by prlimit, I thought it would allow to limit the maximum amount of bytes which a process may allocate.
$ prlimit
[...]
MEMLOCK max locked-in-memory address space 16777216 16777216 bytes
[...]
According to free -h there is about 8GB RAM available in total. So is the default prlimit on my system useless, since a process could easily exceed the available memory and freeze the system (On my fedora system swap is disabled)?
