I kust died in fron of my eyes:
Jan 11 18:08:43 mx postfix-relay/smtpd[16073]: warning: milter inet:[::1]:8892: can't read SMFIC_RCPT reply packet header: Connection reset by peer
Jan 11 18:08:43 mx postfix-relay/smtpd[16074]: warning: milter inet:[::1]:8892: can't read SMFIC_RCPT reply packet header: Success
And the process is gone.
:-(
And on my other server, where I have the standard kernel, the opendkim.verify process has died an hour ago. I really don’t understand all this.
