I have the same concern.
I have had my BI running for about 5 1/2 years.
At first I never ran into the orange clock (didn't even know what it was!) and I was running 20 cameras (dahua/hykvision) at 2160p 10 frames/sec on UI3, now I get the orange clock several times a day or more running 4
Amcrest cameras at 480p at 6 frames/sec.
This behavior started about 2 years ago. The orange clock and I have become good friends.
I posted about it on this forum around that time. I got the standard "check your firmware", etc responses. At that time I had a 4th generation mesh Orbi (
RBK50). I also had a very extensive home automation setup running. In the end I chalked it up to an overloaded router.
Fast forward to today and I am in the middle of a very large remodel. So my home automation network is offline. Further, I have purchased a 6th generation Orbi (
RBK852). One of my apple tablets expired so I replaced it with a new one. I also replaced my Samsung tab with a Samsung Galaxy Tab A (they all run UI3). But even with the reduced traffic and many new components, I get the orange clock just as often as when I was running my RBK50.
Basically I just run the UI3 at 480p (6 frames per second) and have turned down the cameras to 6 frames per second (with matching key frames of course). Its grainy and jerky, but at least it works.
My computer is no slouch. I paid $2,800.00 USD for it from a local shop that purpose built it for BI.
It runs absolutely nothing else other than BI. It never ran any other software, this machine is 100% dedicated to BI and was custom built to only run BI. Here are some of the specs for it (no VM):
I7-10700K (10 cores / 20 threads) (no 'F' or 'T')
16GB RAM
SSD NVMe dedicated for the new, BI, etc.
SSD NVMe dedicated for the OS
HDD
Purple Surveillance WD 8TB for database.
I record BVR, direct to disc
Again, for about 2 1/2 years it all worked well, then the frame rates began to suffer. I just decided it was an overloaded network. But now that I have a new router and very few things on the network and a new router, the behavior is the same. I have reinstalled BI twice. And YES! I restart my BI machine about twice a week. Always have. And YES! I have always tried to keep BI up to date (I pay for support). Currently I am running 5.8.9.5
