Symlink from modules failed

After I installed the beta upgrade I get everyday this message:

Symlink from modules failed
This can result in FATAL failures to your PBX

the symlink will fail if there is a file of the same name in its place. To fix it, delete those files in the sound directory and then hit the apply configuration changes bar again and the error should go away. In either case, that error is not at all fatal. The potentially fatal error is if one of the files listed were extensions.conf or another core critical conf file.

I got a similar error.

"Error Symlink from modules failed"
retrieve_conf failed to sym link:
This can result in FATAL failures to your PBX

Is this a “core critical conf file”?

Is the fix the same as for the sound directory?
e.g. Delete the existing file features.conf

delete (or rename) it and then press Apply Configuration Changes again.

Thanks, that fixed it.
