direct links of old sources may well be a few messages off.

So far quite interesting. But to understand if there is really a bug
May I ask you to send the log from the other machine as well ?

I need it of __BOTH__ machine to understand what is going on there!

Hmm, you can reproduce the issue. Maybe you can send me enough information
so that I can reproduce it here as well. 

I need:
1) Your drbd.conf
2) The drbd-meta-data of both devices on hosta
3) The drbd-meta-data of both devices on hostb (I suppose it has that name!)

This is the way to create meta-data-dumps:

drbdadm dump-md all > meta-data-of-hosta.txt

PS: Please attach the log snipplet as mime attachment, (or try to
    not break long lines with you e-mail client). The same
    holds true for the meta-data-dumps.
