I believe with stock maxdsiz your squid process can not use more than the
512MB limit ... so I do not know where you get 600 from

maxdsiz is not only RAM related but defines the upper limit of memory a
process can use and so I believe your machine does not swap even if not
exist RAM enough for the process (generally) but enough to get to the
limit (maxdsiz) and that might be the reason your squid process crash when
it tries to use more than the 512 limit

what size is your link?

Sure this is not related to your crash and to your link either but
somaxconn is the queue size of pending connections and not the number of
connections and you are probably setting this far too high. somaxconn as
1024 or max 2048 would be more reasonable and nmbcluster I would not set
higher than 128 or 256k

if you eat that up you have other troubles and increasing this values does
not solve them I guess
