When getting a connection refused from the IRC server then ERC keeps
reconnecting infinitely despite erc-server-reconnect-attempts. This is
because erc-server-reconnect calls erc-open, which wipes all local
variables including erc-server-reconnect-count, rendering the increment
in erc-process-sentinel-2 useless.

I just tried connecting to localhost with M-x erc (no irc server
listening there) and I didn't see this behaviour: A few followup questions:
Is erc-server-connect-function customised?
Was this an irc connecton which was previously established, whose
connection was then killed, which erc subsequently kept trying to
connect to?
Was this a connection using tls/ssl or a regular plaintext irc connection?
I'm sure the situation you describe can arise, I may have seen something
similar myself, but merely initiating a connection to a port where no
server is listening does not suffice to reproduce it here - If you can
think of any other details which might help to reproduce this behaviour,
I'd be interested in those too.

You need to reconnect, not connect. erc-server-reconnect-attempts is
only used on reconnects.

Sorry, I should have mentioned that too: Reconnecting from the "dead"
erc buffer that results from attempting to connect to localhost via
M-x erc when there is no server there does not exhibit continuous-retry
behaviour either, at least not here.

That's not a reconnect, since you were never connected.

Well, I issued a reconnect command. What I'm trying to find out is how to
reproduce the problem.

Connect to the irc server by ip, then change the routing so that
connects to the ip are denied.

erc-server-reconnect-attempts is only relevant for automatic reconnects.

Does this patch make the problem go away? It seems to work here.
The problem was that erc-mode was killing all local variables, even when
the mode was already erc-mode : The patch makes it preserve the
reconnection count in that case, which seems to have the desired effect
without adversely affecting anything else.
[ Stomping on the route didn't work for me as the existing connection was
grandfathered in by the kernel: Installing a local ircd and shutting it
down behind the client's back worked nicely though. ]

More information was requested, but no response was given within a
month, so I'm closing this bug report. If the problem still exists,
please reopen this bug report.

It appears to have been fixed in emacs 25 in the definition
of erc-open (similar fix in a different location).
Fix was included in 68cdc4bd7a780641a45b53b8fb71431e2da1a058
