Comment (by AndrewBuck):
I'm not technical enough a user to understand the details in the
discussion above but I will give a couple more datapoints here just in
case it helps in diagnosing the issue. I run a middle relay on version
2.5.10 (but I started seeing these about a week ago on 2.5.9). I had
never seen them before but I kept getting them every hour (about 20 at a
time). After a few days of this I restarted my relay both to update to
2.5.10 and to see if that cleared up the issue. After restart the relay
worked normally for about a week and now I am seeing them again. Here is
one pair of lines (again getting about 20 of these every hour).
Nov 12 07:25:07.334 [Warning] microdesc_cache_clean(): Bug:
Microdescriptor seemed very old (last listed 168 hours ago vs 168 hour
cutoff), but is still marked as being held by 1 node(s). I found 1 node(s)
holding it. Current networkstatus is 0 hours old. Hashtable badness is 0.
Nov 12 07:25:07.338 [Warning] microdesc_cache_clean(): Bug: [0]:
ID=18E0BC920307C0B79F576EDB3473D74D4D1BCA94. md=0x7f8a1bcdaf60,
rs=0x7f8a1d09c290, ri=0x7f8a1d86c200. Microdesc digest in RS does match.
RS okay in networkstatus.
Here is my node on atlas if that helps as well.
https://atlas.torproject.org/#details/55E80F21D6D05CD5FAE52DAEF19EB9E62B8E1F6B
Everything in the logs looks normal before these errors start cropping up,
the only thing even a bit out of place is that in the last heartbeat
before the errors start I am seeing about 8000 TAP handshakes compared to
3 or 4 thousand normally (the number of circuits and NTor handshakes are
normal though).
Anyway, hope this information helps diagnose the problem. I will keep my
relay up like this for a couple more days before restarting in case there
is any other kind of information you would like gathered from it.
