</span>Additional to this, to fully fix the bug 4534 issue we are going to have<br>
to decide if it is reasonable to have extremely large Cache Digest masks<br>
(several tens of GB or memory).<br>
<br>
The caches the bug appears on are all several TB of size (by space). But<br>
even more importantly they are spread over more than 5 cache_dir. So the<br>
2^25-ish limit on entries per cache_dir is not keeping the total<br>
Squid-wide object count within a 32-bit value.<br>
