Max number of Crestron App instances in a program?


 

At one point Crestron had a rule of thumb that? - I think - said max 10 instances?

I am in the process of taking over a troubled job which is needing a reset every day apparently. The code has 30 Crestron App instances.? That was the first thing that stood out to me when I saw the program.... but Tech support said "no problem" to this. Was this limitation just my imagination? Or was this referring to the older Crestron Mobile app that connected on discrete ports? It's a 4 series job so maybe not an issue for 4 series?

In searching for reasons to explain the need for resets I ran the diagnostic tool. I'm not an expert at interpreting error logs but this high number after "nic" gave my cause for concern suggesting high ethernet traffic. I have no other CP-4 to compare this to so I have no idea if this is typical.

CP4>========== cpuload ==========

Thx for any responses

I think that is 95.2%/97.5% idle.

the nic, is your network interface card. seeing a high number on that is normal. Most devices are constantly talking across the network.your error logs would point to the issue more than cpuload.

I have a temporary project with 42 Crestron App instances living in a PRO3 (and all of the iPads on the other end of VPN tunnels) ¨C granted the PRO3 isn¡¯t doing anything other than talking to those iPads and acting as a traffic cop to ¡°patch¡± the iPads to one of 4 other PRO3s depending on what the user wants to do ¨C but no issues.

Back in the 2-series days the Ethernet stack was a hot mess so 10 instances seems about right (if not overly generous) for that platform but with the 3- and 4- the stack is much improved.

I would defer to what Lincoln is saying, and I think that Phil brings up a good point concerning the format if the response:
CPU:? 2.3% usr? 2.3% sys? 0.0% nic 95.2% idle? 0.0% io? 0.0% irq? 0.0% sirq?

It definitely reads to me as 95.2% Idle. all the other items seem to show their identifier after the %...
