Comment (by arma):

 Replying to [comment:7 anong]:
 > This is definiteley a major issue. At the moment it seems impossible to
 run a stable relay on a low-mem device like the Raspberry Pi, since the
 Tor process gets killed by the oom-killer repeatedly. This prevents tens
 of thousands of devices from being stable entry guards or even stable
 exits.

 solution.

 This comment worries me a bit -- I think we are still hoping to have
 MaxMemInQueues be so large that it never triggers in practice, not even
 for raspberry pi relays. Because if it ever does trigger, that means we're
 closing the circuit on a user. So the change in this ticket should *not*
 be interpreted as fixing "the Tor process gets killed by the oom-killer
 repeatedly", yes?
