john_chicago Posted June 25, 2014 Share Posted June 25, 2014 Hi All - I have what might be a medium sized setup (my home is about 3900 sq/ft - and I know there are some 5K+ people out there). I control all lighting, video distribution to 4 zones/tVs, and Audio through Sonos, 8 zones using EV driver)... powered by a HC800 as the main director and I have a HC300 in the 'theater' controlling things there. Every now and then (maybe every month or so...) the system starts to lag and become unresponsive. The C4 remotes, apps, even light switches stop responding, but still seem to queue up, because after 10+ seconds the commands (volume up/down, channel changes, scenes, etc) suddenly start to fire off. An example... my wife presses volume up over and over because nothing happens, and then after 10 seconds it will turn the volume ALL the way up. Another example, I press a button that launches a Kitchen On advanced lighting scene and nothing happens, so I press it again and then some seconds later, the lights come on, and then the scene toggles to off. I'm fairly technical and have done a decent amount of basic programming w/ C4 on my own. I'm somewhat sure I don't have any crazy loops running, I'm not doing anything fancy with loops and schedules. My QUESTION... I'm looking for a good place to start investigating the cause. Anyone have this happen before? Any experts point me to any tools in HC or HCPro that might give me more data? Thanks in advance!! J Link to comment Share on other sites More sharing options...
prabeau Posted June 25, 2014 Share Posted June 25, 2014 I had the same issue that was resolved by changing wifi channel of my network. Was creating interference. Link to comment Share on other sites More sharing options...
neil12011 Posted June 25, 2014 Share Posted June 25, 2014 What I would do, is run the system diagnostics, this is available on pro, which will show you what processes are taking up the most memory. From there it's just narrowing down the root cause. Link to comment Share on other sites More sharing options...

Thanks neil... I'll see if I can get my dealer to run diagnostics for me. The classic *reboot* tends to take care of it too... though I'm having no problems right now. Seems intermittent.

The classic *reboot* tends to take care of it too... though I'm having no problems right now. Seems intermittent. I have had this exact problem and it appears to be related to a poorly written EV driver. Control4 SWAT team looked into my project and confirmed that there are some EV drivers causing these issues. If you have any EV drivers they may be the culprit. Specifically for my system, the MyMovies driver causes this command queue pause every 5 minutes when the driver tries to save my database to the Control4 system storage.

xc420 Posted June 26, 2014 Share Posted June 26, 2014 Next time you have system lag, log in to the HC800 (with SSH client like putty) and run the 'top' command. It's a way for you to look at the processes that are running on the controller. Link to comment Share on other sites More sharing options...
john_chicago Posted June 26, 2014 Author Share Posted June 26, 2014 Interesting... the only EV driver i have is the Sonos driver. SWAT team? Control4 did those diagnostics for you direct... or did your dealer call them? Link to comment Share on other sites More sharing options...

john_chicago Posted June 26, 2014 Author Share Posted June 26, 2014 I'm ashamed to admit that I didn't even consider that you could SSH into your director. This would be amazing... can't wait to try it out. Link to comment Share on other sites More sharing options...
