Chrome hangs after certain amount of data transfered - waiting for available socket

Question

I ve got a browser game and I have recently started adding audio to the game    Chrome does not load the whole page and gets stuck at  91 requests   8 1 MB transferred  and does not load any more content  and it even breaks the website in all other tabs  saying Waiting for available socket    After 5 mins  exactly  the data are loaded        This does not happen on any other browser   Removing one MP3 file  the latest added one  fixed the problem  so is it perhaps a data limit problem

Chrome is a Chromium-based browser and Chromium-based browsers only allow maximum 6 open socket connections at a time, when the 7th connection starts up it will just sit idle and wait for one of the 6 which are running to stop and then it will start running. Hence the error code ‘waiting for available sockets’, the 7th one will wait for one of those 6 sockets to become available and then it will start running.

You can either

1. Clear browser cache & cookies (https://geekdroids.com/waiting-for-available-socket/#1_Clear_browser_cache_cookies)
1. Flush socket pools (https://geekdroids.com/waiting-for-available-socket/#2_Flush_socket_pools)
1. Flush DNS (https://geekdroids.com/waiting-for-available-socket/#3_Flush_DNS)

Our first thought is that the site is down or the like  but the truth is that this is not the problem or disability  Nor is it a problem because a simple connection when tested under Firefox  Opera or services Explorer open as normal   The error in Chrome displays a sign that says  This site is not available  and clarification with the legend  Error 15  net    ERR SOCKET NOT CONNECTED   Unknown error   The error is quite usual in Google Chrome  more precisely in its updates  and its workaround is to restart the computer   As partial solutions are not much we offer a tutorial for you solve the fault in less than a minute  To avoid this problem and ensure that services are normally open in Google Chrome should insert the following into the address bar  chrome     net-internals  then give  Enter    They then have to go to the  Socket  in the left menu and choose  Flush Socket Pools   look at the following screenshots to guide http   www fixotip com how-to-fix-error-waiting-for-available-sockets-in-google-chrome   This has the problem solved and no longer will experience problems accessing Gmail  Google or any of the services of the Mountain View giant  I hope you found it useful and share the tutorial with whom they need or social networks  Facebook  Twitter or Google

Looks like you are hitting the limit on connections per server  I see you are loading a lot of static files and my advice is to separate them on subdomains and serve them directly with Nginx for example     Create a subdomain called img yoursite com and load all your images from there   Create a subdomain called scripts yourdomain com and load all your JS and CSS files from there  Create a subdomain called sounds yoursite com and load all your MP3s from there    etc     Nginx has great options for directly serving static files and managing the static files caching

Explanation   This problem occurs because Chrome allows up to 6 open connections by default  So if you re streaming multiple media files simultaneously from 6  lt video gt  or  lt audio gt  tags  the 7th connection  for example  an image  will just hang  until one of the sockets opens up  Usually  an open connection will close after 5 minutes of inactivity  and that s why you re seeing your  pngs finally loading at that point   Solution 1   You can avoid this by minimizing the number of media tags that keep an open connection  And if you need to have more than 6  make sure that you load them last  or that they don t have attributes like preload  auto    Solution 2   If you re trying to use multiple sound effects for a web game  you could use the Web Audio API  Or to simplify things  just use a library like SoundJS  which is a great tool for playing a large amount of sound effects   music tracks simultaneously   Solution 3  Force-open Sockets  Not recommended   If you must  you can force-open the sockets in your browser  In Chrome only     Go to the address bar and type chrome   net-internals  Select Sockets from the menu  Click on the Flush socket pools button    This solution is not recommended because you shouldn t expect your visitors to follow these instructions to be able to view your site

The message      Waiting for available socket      is shown  because you ve reached a limit on the ssl socket pool either per Host  Proxy or Group   Here are the maximum number of HTTP connections which you can make with a Chrome browser    The maximum number of connections per proxy is 32 connections  This can be changed in Policy List  Maximum per Host  6 connections   This is likely hardcoded in the source code of the web browser  so you can t change it  Total 256 HTTP connections pooled per browser    Source  Enterprise networking for Chrome devices  The above limits can be checked or flushed at chrome   net-internals  sockets  or in real-time at chrome   net-internals  events amp q type SOCKET 20is active      Your issue with audio can be related to Chrome bug 162627 where HTML5 audio fails to load and it hits max simultaneous connections per server proxy  This is still active issue at the time of writing  2016    Much older issue related to HTML5 video request stay pending  then it s probably related to Issue  234779 which has been fixed 2014  And related to SPDY which can be found in Issue 324653  SPDY issue  waiting for available sockets  but this was already fixed in 2014  so probably it s not related   Other related issue now marked as duplicate can be found in Issue 401845  Failure to preload audio metadata  Loaded only 6 of 10  which was related to the problem with the media player code leaving a bunch of paused requests hanging around     This also may be related to some Chrome adware or antivirus extensions using your sockets in the backgrounds  like Sophos or Kaspersky   so check for Network activity in DevTools

simple and correct solution is put off preload your audio and video file from setting and recheck your page your problem of waiting for available socket will resolved      if you use jplayer then replace preload  metadata  to preload  none  from jplayer JS file     preload  metadata  is the default value which play your audio video file on page load thats why google chrome showing  waiting for available socket  error
