Connection reset by peer from REDIS

[wlongabaugh]

Gettng 500 errors from the server. Per the issue at the bottom, Redis in Google cloud might be a bit flaky in App Engine Standard. Wrap the call to catch the exception. File "/srv/main.py", line 359, in root curr_use_per_ip_str = redis_client.get(client_ip) File "/env/lib/python3.7/site-packages/redis/client.py", line 1606, in get return self.execute_command('GET', name) File "/env/lib/python3.7/site-packages/redis/client.py", line 901, in execute_command return self.parse_response(conn, command_name, **options) File "/env/lib/python3.7/site-packages/redis/client.py", line 915, in parse_response response = connection.read_response() File "/env/lib/python3.7/site-packages/redis/connection.py", line 739, in read_response response = self._parser.read_response() File "/env/lib/python3.7/site-packages/redis/connection.py", line 324, in read_response raw = self._buffer.readline() File "/env/lib/python3.7/site-packages/redis/connection.py", line 256, in readline self._read_from_socket() File "/env/lib/python3.7/site-packages/redis/connection.py", line 223, in _read_from_socket (ex.args,)) redis.exceptions.ConnectionError: Error while reading from socket: (104, 'Connection reset by peer')"

Have submitted a support ticket to Google about this, though still need to harden the connection with retries.

Google reply was just to harden the connection attempt. Now tries up to 10 times, backing off with a progressively longer delay after a couple of immediate retries. Keep an eye open for this.
