So, I've got my relay back up on a Raspberry Pi and I'm working on
figuring out the optimizations I made to it, and continuing to tune it.
Out of the box these machines have some difficulty even offering a
couple Mbps, but they can be greatly improved. I will post all details
when done.
I see a fair amount of this, much less than after some tweaks, but it
still happens:
20:27:36 [ARM_NOTICE] Relay resumed [1 duplicate hidden]
20:27:30 [ARM_NOTICE] Relay unresponsive (last heartbeat: Wed Jul 31
20:27:19 2013)
19:50:57 [ARM_NOTICE] Relay unresponsive (last heartbeat: Wed Jul 31
19:50:4
This often happens at the same time as 'arm' (the monitoring program)
may stutter, fail to render a few frames, then 'catch up' or redraw the
screen.
I'm trying to figure out what's going on so I can prevent it. It
doesn't always correlate with traffic - it happens more often when
there's more traffic but can happen even with very little. Tor is
taking about 10% RAM, there's plenty free, and load is under 1.0.
Best,
