@b4n Sorry, git-changebar was an innocent victim.
@techee projectorganizer keeps file descriptors open to lots of directores (my project base directory has many subdiretories). One something tries to open one more file descriptor everything falls down. Why does projectorganizer keep so many fds?
The limit seems to be 1024 on my system, for processes started by my local non-root user. projectorganizer uses more than 1000 of them.
