When you get EAE i/o errors, one of two things is the cause:
- More directories being monitored than the kernel default
- Transcoder temp on a network mount (file locking doesn’t work)
The default directory count for older linux kernels is 8192. Newer linux kernels default to 65535
Procedure here is to figure out how many directories are being monitored then, if necessary, adjust the inotify max_user_watches table size.
