Sorry, this is not my mother language.
---setup:
We have a machine running Redmine with this versions:
Redmine - v2.6.10-3
Ruby -v2.1.9p490
Rake -v10.4.2
Rails -v4.2.5.1
Phusion Passenger -v5.0.6
MySQL -v5.6.30
Apache -v2.4.20
Sometimes, some users, we cant replicate this issue, are working and then user changes account, the server gives them the cookie of other users. I have already tried almost everything I found in StackOverflow, in Redmine.org, and no clue.
I don't know how to be more specific on this, because we cannot emulate the problem in development server.
Extra info: it has two ports, HTTP, and https, not sure if relevant.
Anyone knows if there is any incompatibility between this versions?
Its almost the same thing described in this posts, but we couldn't repair it with the solutions provided, it still happens:

Users take sessions of other users when sessions are stored in memcached (Rails)
Thank you very much.
