 Individual object size problems is not a limit on total RAM size used
 by Squid or its memory cache. You can allocate many GB of RAM cache then
 only store a few million <1KB objects in it.

 Most of the the large object (up to 2GB) problems were solved in 3.0.
 The remainder (>2GB objects) were solved in 3.1.15.
