+### Please describe the problem.
+
+After running for a while, the assistant maxes my CPU. I have evidence
+here that it is just sitting there, doing apparently nothing (transfers
+are finished), eating precious CPU.
+
+Nowadays, I do not let the assistant run on its own, otherwise it makes
+my office noisy because the CPU fan starts.
+
+This makes the assistant and the webapp basically unuseable for me:
+if i want to use its feature, I must remember to shut down the daemon
+every time I am done with it, which seems contrary to the spirit of
+the project. :)
+
+### What steps will reproduce the problem?
+
+It's a little unclear. There was a peculiar crash here (power cable
+yanked out) during a `git annex copy`, which *was* eating up all CPU,
+but mostly through I/O.
+
+That is the purple block in this graph:
+
+![CPU usage during the last 24 hours][cpu-day.png]
+
+Power was yanked out about right after that purple block was gone:
+
+![Uptime in the last 24 hours][uptime-day.png]
+
+Files were copied to an external drive at the time of the crash,
+which explains the high iowait. The last lines in daemon.log are:
+
+[[!format txt """

+"""]]
+
+When the machine rebooted, I logged in, and resumed the transfer using
+`git annex copy`. The assistant was also started automatically during
+my session, but I wasn't aware of that until this morning (7AM) when i
+came back to the terminal and noticed how noisy it was.
+
+At that point i did `killall git-annex` and CPU usage returned to
+normal, as the frequency of the CPU:
+
+![CPU frequency scaling in the last 24 hours][cpuspeed-day.png]
+
+I am trying to see if I can reproduce this problem reliably - I
+just started the assistant again now, and while the CPU usage is
+already high, I will forgive it for now because it's doing its
+initial scans... Let's see what happens in the afternoon! --[[anarcat]]

+This *may* be related to [[bugs/webapp_takes_100__37___of_the_cpu/]],
