Mailbox locked because and idle pop3d process

[Sebastian Calero Laguia]

I have the same problem related to the thread "idle pop3d never times out"
with Cyrus 2.0.16. A user has closed his pop3 client in the middle of
downloading the mails with W2000 and OE. The following times the user has
tried to download his mail the server has responded "IN-USE...", and after
reboot his machine the situation has not changed, and 10 hours later...
equal.

In the server when I execute:

# lsof -i | grep pop3
COMMAND      PID    USER   FD   TYPE     DEVICE SIZE/OFF NODE NAME
pop3d     1512495  cyrus    0u  IPv4 0x48346140      0t0  TCP

srv-du-ops2-dmz5.datadec-online.com:pop3 (LISTEN)


After waiting for a time I kill the 1512495 process and all is OK and the
user return to work again.

There is any type of solution to this problem? Is solved upgrading Cyrus?
