+## Common Issues
 
 ### Too many open files
 
 If you get an error for too many open files, you might wish to exclude your .git, .hg, or similar VCS directories using `-exclude-dir=…`. This is common on OS X and BSD platforms where each watched file consumes a file descriptor.
 
 If you still have too many open files, then you need to raise your process's file limit using the `ulimit` command. Something like `ulimit -n 1024` will probably take care of it. There is also a sysctl based limit which you may reach and need to adjust.
 
+### `filepath.Walk() no space left on device`
+
+As described in [this issue](https://github.com/githubnemo/CompileDaemon/issues/23) it might happen that you run out of inotify watchers which are limited by your system configuration. Please consider increasing them as is documented [here](https://github.com/guard/listen/wiki/Increasing-the-amount-of-inotify-watchers).
