Hi Massimo,

on the 2nd MTA i've VAL to 3072 and clamscan don't give issues but it's
true also that it scan only 7 mail domains

I suspect there are several issues here. One is the number files to be
scanned and the other is the size of the files to be scanned.  The third
is memory fragmentation which may be the most important factor for us.
The change we made to how clam handled memory reduced the fragmentation
significantly, but I don't think it fully eliminated it.

The only current solution we have for fragmentation is to reduce the
number files processed by a clamscan run.

hi,

clamscan at the moment it runs only once per week
and i've seen that about 50% of the times it freeze the server
so i guess i will have to try 3072 soon
