Additional info:

O== WHY is it happening ?

Because the run directory gets deleted and the init script does not recreate it.


O== FIX : 

This is just a simple cruel patch for my system.
I guess you will use something like a 777 for /var/run/clamd.exim
or CLAMD_USER for the chown cmd and of couse a TEST if it's missing would be nice.
