Probably.

It is in the range of a couple of tera-bytes of disk page faults, on a
Squid that has been running for 44 days with a very small request load..

The % values are wrongly calculated. They are off by the amount of
holding blocks.

Not for the % which is not related to the amount of RAM installed in any
way.

An important fact from your cachemgr output (apart from the very high
amount of pagefaults) is that your Squid process is about twice as big
as the installed amount of RAM. I would recommend installing another
256MB of ram in that box (256MB for the Squid process, 128MB for the OS,
networking buffers and the rest) if you want it to perform well.
