hi there,

i'm running a debian wheezy in a chroot at a fritzbox 7230, running with freetz. Running well until the upgrade of version 2.1.7 from debian repros comming up.

after upgrade, the server comes up, but login is not possible.

the libary is still there fritz:~# ldd /usr/sbin/dovecot

    libdovecot.so.0 => /usr/lib/dovecot/libdovecot.so.0 (0x2aaaa000)
    libc.so.6 => /lib/mips-linux-gnu/libc.so.6 (0x2ab48000)

the ulimit i have tried, but without success.

I have no idea to solve this. The question is, is it possible a bug in debian wheezy mips or in dovecot. Hopefully someone can point me in the right direction.

thanks and regards micha
