-ERR Timeout while obtaining a lock on

Greetings All,

I have a single user trying to use cPanel's webmail interface but is encountering difficulties. She has in the area of 1000 e-mails in her inbox and finds any of the interfaces to be exceedingly slow. When I tried to pull her e-mail off the server I was unable to do so.

After some troubleshooting I suspect that the amount of time needed to open her mailbox, count the number of mails and the Octets is exceeding a 60 second timeout in cppop. This is demonstrated by Telneting to the mail server and trying to access the mailbox manually. This produces:

+OK POP3 sdcp6 [cppop 20.0] at [xxx.xxx.xxx.xxx]
user username@ourdomain.com
+OK Need a password
pass *******-ERR Timeout while obtaining a lock on /home/ourdomain/mail/ourdomain.com/username/inbox


Connection to host lost.

What happens is that upon entering the password and hitting <Enter> the server "goes silent" for EXACTLY 60 seconds and then returns the -ERR timeout. So we are unable to retrieve her e-mail.

Is there a setting that I can change to increase that 60 second timeout so the server has enough time to scan the mail file or some other solution to get this user back in business?

Thanks in advance for your help on this.
