    how many space it will cost?

    KiB Mem:   3010684 total,  2877212 used,   133472 free,   127428 buffers
KiB Swap:  3071996 total,      224 used,  3071772 free.   826616 cached Mem

    i free some space it works~~~

    ENOSPC can also mean you're running into one of the system limits:

    $ sysctl -a | grep ^fs.inotify
fs.inotify.max_queued_events = 16384
fs.inotify.max_user_instances = 128
fs.inotify.max_user_watches = 8192

    I'm going to close this as it's not really a bug. The error message could perhaps be a little nicer but the kernel doesn't tell us anything besides that ENOSPC error.
