Hum,
With some more play with strace, i've attached a pop3d process:
This "(Resource temporarily unavailable)" is harm ?

Server during work time, is very very busy
Before change postfix master.conf configuration, I have:
lmtp unix - - - - - lmtp
wich I belive it's the defaults 'cause I didn't changed them.
Like this it's unlimited right?
Tunning to:
lmtp unix - - n - 3 lmtp
means that postfix will only have 3 lmtp process's to dbmail, right?

That's the process pool's locking code.
How many lmtpd processes are you running???
You will rarely need more than a few lmtpd processes (2-4), unless you have
a
very busy server.
Even then: excessive amounts of lmtpd processes or even multiple simulaneous
dbmail-smtp based injections can lead to deadlocks in mysql during message
insertion. I've been trying to fix that recently. Update to the latest in
the
2.2 branch to include those changes. Your problem is not caused by any
post-rc2
changes.
Narrow your lmtp bandwidth by tuning the maxproc field in master.cf:
lmtp unix - - n - 3 lmtp
on your receiving postfix installation.
