[tor-relays] Ubuntu is killing tor when getting low memory

Hi Folks,

im running many relays which are doing a nice job. But i have also some smaller relays outside which have just 256mb. They are performing quite quell - but on one relay im facing issues which i think you may help me.

this relay seems to ran out of memory from time to time (2 to 5 days) and i found out via dmesg, that ubuntu itself is killing the process to free up memory. the swap is used, but far away from full.

as this stops tor immediately its bit annoying that i need to restart the releay without any reason.

is there any way to tell ubuntu or to prevent that the tor process is killed for freeing up memory?

i dont care about other processes as this machine is for tor purposes only.

thanks for your expertise! Geri
