machine freezes are almost always due to kernel issues, not
application software like Squid. Application software should at most
be able to temporarily slow down the system, not cause it to freeze.

What should be noted is that Squid during "-k reconfigure" or "-k
rotate" may fork a number of times (once per helper process), which
will stress your VM system considerably. See the Squid FAQ 8.8 fork:
(12) Cannot allocate memory
<url:http://www.squid-cache.org/Doc/FAQ/FAQ-8.html#ss8.8> for some
discussion regarding this feature of Squid. Maybe your kernel has
some issue with fork of very large processes or running out of swap
space casuing the freeze instead of an error which it should give in
such conditions..
