Bug Description

Could it be possible to update libapache2-mod-cband in Dapper to the version in Edgy?
We're running apache2 hosts here with mod-cband enabled, and it just gives a blank screen when going to http://<ip>/cband-status, and, as we found out later after a lot of searching, it keeps on spawning new semaphores, which never gets deleted. After a while, the max. nr of semaphores on the server are reached, and reloading or restarting apache results in a segfault. Only rebooting makes apache come back up. I backported mod-cband from edgy, and the status page loads just fine, and shared memory segments do not increase anymore either. It's been running here on production systems for quite some time now.

Thanks in advance!
