Каждый день я получаю электронное письмо от моего приложения на python flask со следующей ошибкой:
WriteError: error 5 from memcached_set: (54648992) SERVER HAS FAILED
AND IS DISABLED UNTIL TIMED RETRY, host: 127.0.0.1:11211 ->
libmemcached/connect.cc:612
Memcached запущен, и на клиенте и на сервере установлен адрес 127.0.0.1. Когда я вручную проверяю соединение, кажется, что все в порядке. Это случается только периодически.

# This configuration file is read by the start-memcached script provided as
# part of the Debian GNU/Linux distribution.
# Run memcached as a daemon. This command is implied, and is not needed for the
# daemon to run. See the README.Debian that comes with this package for more
# information.

# Be even more verbose (print client commands as well)

# Start with a cap of 64 megs of memory. It's reasonable, and the daemon default
# Note that the daemon will grow to this size, but does not start out holding this much
# memory
-m 64
# Default connection port is 11211
-p 11211
# Run the daemon as root. The start-memcached will default to running as root if no
# -u command is present in this config file
-u memcache
# Specify which IP address to listen on. The default is to listen on all IP addresses
# This parameter is one of the only security measures that memcached has, so make sure
# it's listening on a firewalled interface.
-l 127.0.0.1
# Limit the number of simultaneous incoming connections. The daemon default is 1024
# -c 1024
# Lock down all paged memory. Consult with the README and homepage before you do this
# -k
# Return error when memory is exhausted (rather than removing items)
# -M
# Maximize core file limit
