Change of severity level

[s-wust]

When this event was introduced, it was logged as warning as it is non-critical for dovecot's stability
It was (maybe by accident...) elevated to error when the i_info()/i_warning()/i_error() calls where replaced with their e_*() equivalents
(see 66ddc39)
To prevent flooding error logs with non-critical errors, it should be reverted to warning

Hmm. Maybe .. but why are you getting those errors/warnings anyway? It's not really expected unless one of the login processes crashes or something. Are you maybe using SMTP or some other external auth that connects to Dovecot?

I can't really figure out. I've seen nothing suspicious in my logs.
And yes, I'm using Postfix SMTP AUTH through Dovecot.
