I would hope the limit is more close to 4 GB in this case.

There was a bug in earlier Squid version where it was not detected if a
value larger than what fits in a size_t is specified for this directive
and many other directives. This was corrected in Squid-2.5.STABLE5 to
reject such configurations:

It is possible there still is issues in the range 2 GB to close to 4 GB. I
hope not but I have not actively tested.
