I have 2 Dovecot servers (as clustered on ocfs2). I
sometimes get
some errors since I installed the sieve plugin.
Sometimes though they are not actually quota exceeded,
I get "Quota
exceeded" error messages.
There is no any disk or file system error/warning.
Where do you expect such a warning to show up? Did you
check all
relevant filesystems with "df -k" and "df -i"?

Inodes are 63% used (max value of results). These errors
shown in dovecot logs.
