Once a month is overkill, and unlikely to be useful. :) With server or enterprise grade hardware, it'll support "ECC" memory. That has extra memory chips + supporting circuity on the memory board so it can detect + correct most errors which happen without them causing problems. For the errors that it can't *correct*, it'll still generate warnings to your system software to let you know (if you've configured it). If you do get such a warning - or if the system starts acting funny like you saw - that's when you'd want to run memtest on the system. --- The other time to run memtest on the system is when you first buy or receive a new server. You'd generally do a "burn in" test of all the things (memory, hard disks/ssds, cpu, gpu, etc) just to make sure everything is ok before you start using it for important stuff.
