After some test, it appears this problem happens when cyrus is launched
from the command line and then stopped using Ctrl+C hotkey.
In this case, all processes (master and imapd/pop3d/lmtpd children)
receive a SIGINT signal.
In the standard case, cyrus is stopped by sending a SIGINT signal to the
master process which send the SIGTERM signal to all imapd/pop3d/lmtpd
children, no problem in this case.
I don't understand why but it seems some locks are not properly released
in the Ctrl+C case.
Any clue why this problems happens ?
The lock problem can be solved after by launching ctl_cyrusdb -r.
