Lock file not removed

[aseques]

Hello, I am trying to develop an script to manage some domains. I'm facing a probem with the lock file.
With version 1.0.0 the lock file (in /var/run/ispcp.lock) is removed when the system stops the processes.
After upgrading to 1.0.3 (from trunk) the lock is never removed.
I've been looking and couldn't find the process that removes it, I suppose that it should be the same that launces the domain/mailbox/etc.. creation.

Thanks
