Hi guys,
Just upgraded my embedded pfsense to 2.3.
I have problems getting to the box (web or ssh) it just time outs.
On the web I sometime I get Nginx 504, sometime, just nothing.
Eventually I got logged in, try to check what's going on.
I have open Diagnostics->System Activity page, and start monitoring the
network traffic.
There is Java Script that updates the page content every 2.5, but actual
response in my case was more then 15 sec.
So I ended up with +20 pending requests to /diag_system_activity.php.
I don't think that setInterval is a good option here. Especially when you
don't know how long it will take for the request to complete.
My suggestion is to use setTimeout like this:
Yeah that's what 2.2.x and prior used.

Hi Chris,
I've checked the commit.
If you guys are going to use mutex, I think setInterval is better option.
I'm working on realtime software, implementing long polling. I found for
my case setTimeout on the $.ajax.complete event was better option. But
every project is different :)
I found similar calls on a few other places.
The dashboard for example. And any page that shows real time information
too.
On the dashboard is actually worse, because each widget calls it's own
data feed.
On my embedded system, webConfigurator has Default Max Processes set to
2, which means, there will be blocking calls from the different
collectors on the dashboard page.
I know it's not easy to deliver all the data for the widgets with one
single call.
I know that all the problems I have are because of the slow CPU on my
system.
Unfortunately I'll have to roll back to 2.2.x version.
Thank you for the great job you guys are doing.
Rosen
