title: Redis: phpRedis client connections increase until they reach 11-12
body: <p>I have substitute my memcache with Redis. I use the phpredis client and the pconnect () for connecting. 
  I have also created a Redis class which implements the singleton pattern, but I keep on getting new client connections after a few refreshes of the home page.</p>
  
  <p>More specifically, I have an application which gets some values from redis by given keys. 
  When I start redis-server I have 0 clients connected. I refresh the page and 1 client is connected. In the second refresh 2 clients are connected. After 2-3 more refreshes 3 clients are connected and so on, until it reaches 11 sometime 12 clients. Then it stops to increase their amount.</p>
  
  <p>The time to render the home page is more or less the same (also with memcache) and it doesn't consume more memory, but I was trying to find why it does have this weird behavior.</p>
  
  <p>I run my application locally on MAMP 2.0.5 and I have redis-2.4.7.</p>
