My home server sits in my loft managing comms with the outside world; 
yesterday it overheated (not a surprise) and went down. On reboot after 
cooling it came back up with the grub_calloc problem, so like Tom I 
reinstalled after which it appears to be OK.

BUT because I have no idea why the original problem occurred, or why a 
reinstall fixed the problem, I have no idea if this is a permanent fix, 
or if I have a system which is liable to fail to reboot again in the 
future. Does anyone know? It's a very simple single drive system with 
legacy boot. I run it with security updates on auto, and check for other 
updates manually once a week or so. Should I change this pattern for a 
while while possible grub problems are sorted upstream?
