I can confirm this bug on my wheezy system.
Each morning my apt-cacher-ng system starts some processing and CPU usage
goes up to ~30%. The process lasts at least 2 days ( i killed it
afterwards).
As the system is monitored, i can tell some things:
There is no increase of Disk IO but the number open inodes goes up from 7k
to 15k and the numberof threads goes up by ~70.
Hope this might help?
