I achieve to reproduce it. It's not caused by the patch.

This happens if limits exceeds for user having no interactive session. More precisely if utmp database is missing records for given user.

Reproducer:

1. Enable quotas on a file system and set limit for a user.
2. Start quota_nld service.
3. Log in as the user and start a screen session (make sure no other sessions
   for that user exist).
4. Run a delayed command that exceeds the limit. E.g:
   # sleep 3; dd if=/dev/zero of=file bs=1k count=200
5. Detach from session and log out before the command takes effect (3 seconds
   in this example).

You will get the error message in system log because quota_nld daemon could not find a record for the user in /var/log/wtmp.
