Please describe the problem.
I've been running git-annex in the background for a few weeks now (my laptop is at home, occasionally gets suspended, but not for the past few days), and this morning (around 9:30am), I noticed I could hear its fan. Looking at CPU usage in htop, "git-annex webapp" was using ~18% and "git --git-dir=/home/flowblok/annex/.git --work-tree=/home/flowblok/annex -c core.bare=false cat-file --batch" was using ~46%.
The repository is in direct mode. It has one remote which it copies to over the network with "annex-rsync-upload-options = --bwlimit 10". The last fsck ran at 4am, and finished (with one failure, which I can easily recover from) by 4:30am (I guess I should find out why it didn't notify me in any way).
What steps will reproduce the problem?
Not a clue! Though hopefully I've given enough information below for you to figure out what went wrong: let me know if you need anything else.
What version of git-annex are you using? On what operating system?
Debian Jessie

# (ands lots more of the same)
The most likely reason for the assistant to use CPU like this is when it's running the expensive transfer scan to find files that need to be copied from/to remotes. That has to consider every file in your repository's work tree, and uses git cat-file to extract information from the git repository to see where the file is currently located. This is normally only done when the assistant starts up.
.git/annex/daemon.log will show when the expensive transfer scan starts and finishes. Look for "starting scan" and "finished scan" lines. Or, open the webapp and look to see what activities it says it's performing.
This is on jessie with 5.20151208-1~bpo8.
git-annex webapp and git --git-dir=.git --work-tree=. --literal-pathspecs -c core.bare=false cat-file --batch are using considerable CPU time. The strace appears to be this:
[pid 29222] open(".git/annex/journal/1e9_9e8_SHA256E-s109439--4df4c11870535f09bea79e309ac1d3de0e3ed5054900257c212277c0dc84290e.odt.log", O_RDONLY|O_NOCTTY|O_NONBLOCK) = -1 ENOENT (No such file or directory) [pid 29222] write(15, "refs/heads/git-annex:1e9/9e8/SHA"..., 119) = 119 [pid 29222] write(7, "\1\0\0\0\0\0\0\0", 8) = 8 [pid 29161] read(7, "\1\0\0\0\0\0\0\0", 8) = 8 [pid 29222] read(18, "fb6b750de51cf247dae90279745c2478"..., 8096) = 341What's more, the webapp shows that it's only synced to one of the two remotes, despite both being available. The log has nothing about kicking off a sync run.
I also wonder if this is and Assistant having a child git cat-file --batch do the same thing over and over and using a lot of memory are the same issue.
