Still no luck with this. I have followed the debuggind guidelines of dovecot wiki (http://wiki2.dovecot.org/Debugging/ProcessTracing) and executed the following:
strace -f -tt -o strace_dovecot -p 15426
15426 is the PID os /usr/sbin/dovecot. I attach you compressed the log of the strace . Hope this help to solve this issue.

What am I doing wrong? I have migrated a identical server fromdovecot 1.2 to dovecot 2.0 without this problem.
