Hello! During memory pressure and/or high load, journald may crash. This is probably due to design using mmap but it should really not do this.
On 32-bit systems, we are seeing such crashes constantly although the available memory is still gigabytes (it's a 32-bit userland running in a 64-bit kernel).
