I encountered this error on FreeBSD 9.3 with dovecot2-2.2.13_3
Short version; vsz_limit is 18,447 PB and it ran out of RAM. Suggestions for
change?

Check the message again - it says vsz_limit=256MB
Background: I’m in the only user on this system, but this server is accessed by
my phone, my laptop, my tablet, and perhaps a web interface.
But there are some interesting values when I look at the output of doveconf.
Specifically, vsz_limit is 18,447 PB… yeah, that’s pretty big.
service imap-login {
vsz_limit = 18446744073709551615 B
}
According to your log it was process "imap" what ran out of memory. You
are showing configuration for imap-login - they are not the same thing,
see http://wiki2.dovecot.org/Design/Processes
Not sure if this behaviour is a bug or something that is to be expected
when you run out of VSZ limit in imap process - that needs to be
answered by someone more knowledgeable
