You need more swap, and probably also enable the sleep_after_fork
directive.

The UNIX way of starting a sub process (helper) is a bit odd, and can in
worst case require a temporary memory resevation of 40 times the normal
amount of memory for Squid while it is starting the helpers.. It's just
a reservation, not acual use, but still needs swap space for the
reservation to succeed.

with sleep_after_fork enabled this can be limited to 2 times the normal
amount..
