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, -Gordon M.
