We have a SPA that runs SockJs both client and server (NodeJs) side. For Windows workstations we have no problems maintaining web socket connections to servers deployed in Windows Azure. But for some colleagues using Mac OS X workstations they are experiencing in recent weeks frequent random disconnections for Web sockets. Happens on both Chrome or Firefox, so it appears to be at a lower OS level thing.
As far as they know there were no updates to OS X that might have affect the network stack. Don't seem to find any issues on SockJs either. Any troubleshooting tips for OS X?
