During some rigorous testing, one of our scripts is making around 250K
GET requests (all different paths) with basic auth. Before this test,
all users are able to login but after the test, only a couple of them
are able to login. For all other valid users I see unauthorized
message in the logs (mentioned below).

I have changed only the following auth settings
auth_cache_size = 50000
timeout = 3600 ;seconds

I'm currently on 1.0.2.

Please help.
