[Dovecot] new configure-option --disable-index

[Marten Lehmann]

Hello,

this problem is really scary. It once worked with lock_method set to the 
default and login_process_per_connection=yes. But really only once. I 
logged in again and then the process died again after the server 
responded with "+OK Logged in.". But even this doesn't happen all the 
time. It also happens very often, that after this "+OK Logged in." 
nothing happens. I can enter whatever I want, but the server doesn't 
respond any more, but the connection doesn't die.
What also might be of interest: Although I'm testing all this for later 
use with NFS, right now I'm only working on the local harddisk, with no 
NFS involved. I don't really know whats happening in mail-index-lock.c 
line 252, I hope Timo has an idea.

Regards
Marten
