That error message is confusing. The inotify_add_watch() system call returns ENOSPC. Usually, ENOSPC means "No space left on device", and the strerror() library call translates it to that. However, in the context of inotify_add_watch(), it means: ENOSPC The user limit on the total number of inotify watches was reached or the kernel failed to allocate a needed resource. So, it seems that you allocated many many inotify watches and need to increase the limit.
