You can look at the parent process of each and see that one half spawned the other half, or you can look at the environment variables for each to see that there are two processes operating in the same directory for each directory where there's an issue. $ echo "$(for pid in $(ps | grep 'git fetch' | grep -o '^[0-9]*'); do ps -p $pid -wwwE | grep 'GIT_DIR=[^ ]*' -o; done)" | sort GIT_DIR=testdir14 GIT_DIR=testdir14 GIT_DIR=testdir32 GIT_DIR=testdir32 GIT_DIR=testdir47 GIT_DIR=testdir47
I've searched through the mailing list, but this doesn't seem to be a known issue. I've only seen this occur on macs (and with a good deal of regularity). It doesn't occur on my Ubuntu box.
