I'm having a problem with my FBA in production envirement, when I choose the "FBA User Management" option it tooks a lot of time to respond (I have just 20 000 users)... But when we choose to find a specific (Search) user it tooks a huge amount of time and share point goes down showing "Sorry somthing went wrong" with an Id of correlation
Failed to read resource file "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\Resources\FBAPackFeatures.fr-FR.resx" from feature id "(null)".
Failed to open the language resource keyfile FBAPackFeatures. [Forced due to logging gap, cached @ 05/16/2018 10:38:19.79, Original Level: Verbose] SQL connection time: 0.110053998923011
Application error when access /_layouts/15/FBA/Management/UsersDisp.aspx, Error=Time out

I have share point 2013, running on windows server 2012
Any Ideas please
