NoVNC Connection timeout with Firefox 15

Description
I'm using Foreman with libvirt with about 15 vms. I started getting Connection Timeout when displaying the noVNC. I managed to fix this problem by increasing some values in /usr/share/foreman/public/javascripts/noVNC/rfb.js:
def_con_timeout = Websock_native ? 5 : 15,
'disconnectTimeout', 'rw', 'int', 5, 'Time (s) to wait for disconnection'
- Priority changed from High to Normal
do you have any idea why would it take more than 5 seconds to open a connection? is it a slow network?
I think libvirt may be too slow to response. But I think it is irrelevant what is causing such lag. I would expect there is no harm done if the timeout is increased. On the other hand, there is harm when it is too low!
On the other hand, from what I've found, TCP handshake sends 5 SYN packets, waiting no more than 200+800+1600+3200 = 5800ms.
ok, care to send a pull request / patch? :)
- Subject changed from NoVNC Connection timeout when using libvirt to NoVNC Connection timeout with Firefox 15
- Target version set to 1.1
ok, the real cause for this issue is described here:
https://bugzilla.mozilla.org/show_bug.cgi?id=789018
summary, FF15 opens too many connections at once, so the timeout fix (as shown in this patch and still waiting for a pull request) would be a workaround only for FF15.
