Gentoo hardned-kernel (grsecurity+pax+selinux), the Debian 64-bit is 
running vanilla. It doesn't show the error, it just kills that process.

Yeah, I wondered why tranferring small IMAP folders reguire nearly 16 
gigabytes of RAM. Too bad those servers only have 2. Again dovecot gets 
stuck until connection will timeout itself.

512MB is the limit in the dovecot-config so that it doesn't get on 
rampage. Yet it apparently tries to do that.
