seems use hover function bit wrong.
first, if output log see when call functions, can see mouse leave not calling, because fire should on element class submenu. so, element inside toggle , when leave leave element toggle class, raise hover function again.

in case fadeout animation delay, , hide element after calling show function. in case hide hide element, , show instant.

to solve should use hover handlerin, handlerout params , show in handerin , hide in handlerour.

sample: 

$(document).ready(function() {    $(".toggle").hover(function() {      console.log('hover in');      $(this).find(".submenu").first().show();      $(this).addclass("active");    },function(){      console.log('hover out');      $(".hlavnakategoria").removeclass("active");      $(".submenu").hide();    });  });

recently upgraded our ec2 instances c3.large in order boost more unicorn workers handle increased traffic our site. (6xworkers per machine - 2 ec2 instances). when did this, started seeing duplicate records being created! looks somehow, maybe 2 unicorn workers attempting process same request? in nginx logs see 1 [post] request particular rails controller - yet 2 records being created in database. i'm hitting kind of race condition issue - have no idea how debug this. doesn't happen time, when it's frustrating well. noticed 2 database records within 5 seconds of each other. (and yes disable button when user clicks submit button). unicorn 4.8.2 ruby 1.9.3 rails 3.2.14 any great! thanks! although may not fix problem, upgrade ruby 2.0.0. there blog mentioning idea upgrade ruby 2.0.0 if using unicorn. for example: https://www.digitalocean.com/community/articles/how-to-optimize-unicorn-workers-in-a-ruby-on-rails-app specifically: if using ruby 1.9, ...
