Don't relay on /dev/urandom, it will use 100% of CPU and take several minutes if your RAM is big. YET, /dev/shm has a relative size in modern Ubuntu/Debian distros, it has a size that defaults to 50% of physical RAM. Hopefully you can remount /dev/shm or maybe create a new mount point. Just make sure it has the actual size you want to allocate. | |
