25824	Assertions in libmemcached when multiple django.core.cache.backends.memcached.PyLibMCCache backends used	Michał Łowicki	nobody	"We're running Django 1.8.3 via uWSGI with threads enabled (uWSGI 2.0.11.5, configuration - [https://gist.github.com/mlowicki/9a5042b5411537a51bbf]).

When two backends using 'django.core.cache.backends.memcached.PyLibMCCache' are added and are used (each box is handling at least hundreds requests per second) then in uWSGI logs we're seeing lots of [https://gist.github.com/mlowicki/a8b3dbd98f32dc40c4eb] and application is misbehaving throwing 500s. When launched in second datacenter with much less threads then problem is much smaller but still exists (uWSGI configuration - [https://gist.github.com/mlowicki/cbd18c689c3e2f838bf0])

Tried with pylibmc 1.4.1 and 1.5.0. Running on Debian Wheezy."	Uncategorized	new	Uncategorized	1.8	Normal				Unreviewed	0	0	0	0	0	0
