Today I started thinking it has to be because some file descriptor is  
opened as fd 5 initially, but it's set close-on-exec flag and so when  
login process execs it probably opens epoll fd as 5 and then trying to  
epoll_ctl() it it fails. But I kind of forgot to check it today.  
Although in any way that would require something like SIGHUP to happen  
just before the failure starts..

Can you anyway check if reversing this patch solves the problem for  
you?  http://dovecot.org/list/dovecot/2009-October/044140.html
