Since we upgraded to 2.0.9 (from 1.10 stock CentOS release), we are getting some errors with pop3. When the machines get busy, now and then it start with the following:

Do you see any warning messages in logs containing "client connections are being dropped"?
I did not see it on any machines. But for this specific one, I got the following after those errors, before restarting dovecot:
