Roundcube | Strange error

HI!
I'm working for years with ISPConfig, for my needings it is perfect.
Mostly i have the latest builds in a live configuration.

--

Since yesterday, i have a really strange error:

Code:

Oct 10 21:55:07 ds082 postfix/trivial-rewrite[12766]: fatal: proxy:mysql:/etc/postfix/mysql-virtual_domains.cf(0,lock|fold_fix): table lookup problem
Oct 10 21:55:10 ds082 postfix/trivial-rewrite[12770]: fatal: proxy:mysql:/etc/postfix/mysql-virtual_domains.cf(0,lock|fold_fix): table lookup problem

Since that time, i was starting too search Google. I can't find ANY suggestion.
My system was working since that time.

Can someone help me? Thanks in advance
