[Dovecot] "Out of memory" error in 1.0alpha3

[Sergey A. Lipnevich]

Timo,

In regards to the conversation below, does this item in release notes 
for 1.0.alpha4 mean that you found the problem?

 - epoll was broken with 64bit systems

With 1.0.alpha3, I'm still seeing an "Out of memory" error with one 
Apple Mail user (but the user says everything works just fine), so we're 
planning to upgrade to 1.0.alpha4 and take it from there.
Thank you!
Sergey.
