+Hi.
+
+trying to manage my collection of digital music files using git-annex. The collection (113 gigs of flac files ripped from my CDs) should be stored on my three different machines and updated on all of them, if I add or change a file on only one of the machines.
+
+### Please describe the problem.
+
+Added a new external USB disk for sneaker transfer via web app, yesterday.
+
+Now for no apparent reason, after startup/login, git-annex would start and quickly suck up all available RAM. This is on a fairly well equipped machine (16G physical RAM, i5-2400), yet "top" tells me that there is one git process that sucks up more than 20G and climbing. It looked like this:
+
+    git --git-dir=/home/user/Sync/Audio/.git --work-tree=/home/user/Sync/Audio -c core.bare=false log refs/heads git-annex..13d365f16ffdb5a393f66362b840d3f21bb4c59c --oneline -n1
+
+The computer then slows down, grinds to halt, becomes unresponsive and it's difficult to even login on the console.
+
+Then, the OOM killer kicks in and kicks the git process, but git-annex quickly starts another which does the same.
+
+### What steps will reproduce the problem?
+
+I don't know what caused it. The symptoms remained after a reboot, "git annex watch --stop" didn't help either, since I'm a dumb web app user, I'm not sure if that's the right command to use anyway.
+
+For now, I have removed git-annex from the system.
+
+### What version of git-annex are you using? On what operating system?
+
+Last installed version: git-annex 5.20140127.1 on Ubuntu 13.10, amd64.
+
+### Please provide any additional information below.
+
+I'm fairly unsure where to look for the cause and what logs to provide you with to help fix this. Just guessing that it could be a symptom, but the daemon.log is full of entries like this:
+
+[[!format sh """
+# If you can, paste a complete transcript of the problem occurring here.
+# If the problem is with the git-annex assistant, paste in .git/annex/daemon.log
