Preliminary idea: this is a very old version of Dovecot. Before diving 
into debugging sessions maybe you could do yourself a favour and update 
to a more recent version, such as 1.2.6? 

Now, when you realise that some process (is it imap-login or imap?) is 
down can you log into the server and confirm that, using ps or another 
tool? You say the log files don't tell you anything. Can you set 
auth_debug = yes and/or mail_debug = yes? Maybe that can give you a 
clou.

And how about the LDAP server? Being unable to log in could have 
something to do with the authentication backend. How does your 
dovecot-ldap.conf look like? Could it be that the LDAP lookup somehow 
crashes an IMAP-related process?

A newer, better Dovecot version will probably help you a lot with the 
debugging. It may even make the error go away. You should seriously 
consider upgrading.
