All this implies is that when squid did an accept() on a connection, it got
returned EPROTO. It is highly unlikely that squid can _cause_ this to
happen as this is being returned from your kernel protocol stack, and is
more likely to be either a bug in your OS, or some tuning issue - you could
be out of resources, maybe file descriptors (accept creates a socket, which
uses an FD), or some other configurable OS parameter.

To see squid's FD usage, use the cache manager. Obviously, you could run
out of FD's for the _whole_ of your system if your using your squid server
as a server for other things too.

Have a look in your OS docs, or maybe your man pages for accept (section 3
of most man pages). If nothing else, try temporarily increasing your FD
limits and see if the problem goes away/diminishes.

However, generally, EPROTO is due to things like the client setting bad IP
options - and it shouldn't slow down your system when it happens, so I'm
still not sure this is the correct answer.
