blue iris suddenly a memory hog and at 100% cpu usage

Guitarist155 · Nov 22, 2017

Mine is now holding around 55%. Up from 8% before and 3.5Gb ram, up from 2.77 before.

That certainly could be the Intel graphics driver memory leak in play here, if you don't have many cameras. It appears to take about a day to gain 1 GB of memory usage with "limit decoding" turned off. That is pretty slow but it rises steadily which is usually a sign of a memory leak.

Or it could be a memory leak in Blue Iris itself that only some of us experience due to different configurations. For what its worth, my BI 4.6.4.12 CPU and memory usage has been stable and normal. You could try downgrading Blue Iris to an earlier version using one of the update files linked earlier in this thread to see if that fully solves the problem. If the memory usage continues to rise like it has been doing for the last month then that really points the finger at the Intel driver.

I don't believe mine is a memory leak as I can immediately recreate the problem after reboot. Reboot BI PC, login, launch BI, play back recordings. CPU immediately pegs at 100% and system goes intermittently unresponsive. Same activity before the upgrade would push CPU somewhere between 45 - 55%.

Guitarist155 · Nov 22, 2017

I do not believe mine is a memory leak either, but is definitely directly related to the latest update, been running fine for almost a year, new update and all of a sudden it spikes, it takes a few hours to climb to about 70% then goes to 55 and has stayed there.

The computer can handle it, E3-1245 V5 8 thread 3.5ghz with Intel microcode patched, 32Gb ddr4 2133 ecc. I’m betting if it was lower power I would hit 100% with this issue.

I am getting the same behavior with a recent build. A reboot will cause CPU usage to hover around 15% (at the start). After a little while, the CPU usage goes up to 55% or so.

Downgrade to 4.6.4.11.

Guitarist155 · Nov 22, 2017

Update: turns out I in fact did NOT have Limit Decoding turned on. Interesting! So I am now at 1% CPU usage with 19MP recording 24/7. Odd that this last update would suddenly skyrocket when I’ve only been hovering around 8% before.. but 1% is wonderful.

Mine hasn't changed either with recent updates. If anything it might be a little less but I've also made some cam changes recently so I wouldn't swear to the latter. I'm also using older 3rd and 4th gen i5s that are around the same vintage as yours. Definitely not higher and definitely not leaking over time.

Happy Thanksgiving, everyone! Just a quick note to report that I downgraded (installed an old version) to 4.6.3 and it made no difference at all. Still high CPU and pegged when playing back video. I also checked my graphics driver and its still a 2016 version, so that didn't change. Something else is going on here. Will dig in after Thanksgiving. #gocowboys #dezcaughtit

So, I have tried ...

1. rolling back my graphics driver ... didn't help
2. rolling back to earlier versions of blue iris ... didn't help
3. wiped my computer, and installed a clean version of windows 8.1 ... didn't help
4. rolled back to an old version of blue iris on my new clean windows install ... cpu and memory were lower than ever, even when recording ... for about 2 days. Now it's back to 100% cpu after starting up blue iris

this is frustrating

Did you use the same BI configuration on your new install ? If so and if you have the backup of the previous config, I would restore that as well. Sometime you just can't roll back the BI version, you must restore the registry config as well.

Is it really clean? What Media are you using... upgrade to 10 then do a clean install with the media creation tool

CorporalCuddler · Nov 26, 2017

I did the upgrade to Windows 10.

I then used the media creation tool to install a clean version of windows 10.

I then installed blue iris.

I have had for the last 9 months or so, 5 cameras setup in blue iris. While I was adding the 5th one, the cpu hit 100%.

I guess I'm back to downgrading blue iris again.

This is not fun.

So are all 5 cams same type ? Did the 5th one make it spike or what...hard to help when you don't give much details.

I am happy to give details. I have spent a lot of time trying to figure out why blue iris quit working properly. That's why I'm here.

I have four of the same camera - Hikvision 2042.

The fifth one is a Dahua ... I'm not certain of the model, and am not in a place where I can check at the moment.

Anyway, I disabled the Dahua camera to see if that particular one was causing the issues ... after about 2 minutes of running, the cpu jumped to 100%. So, that particular camera doesn't appear to be the cause.

So maybe you should consider the display driver again now that Win 10 is on the machine. Did you look at what driver version you have now?

I'm testing out a different graphics driver right now. So far, after about 20 minutes, it's acting like it did before these problems started. But, for 2 days it looked like the problem was gone before. So, I'll be back if the problem comes back, or after a few days of it running. Either way, I'll come back here ...

By the way, I really appreciate everyone's input.

Same issue here, comming from an win7 nu box which was rinning fine on the latest build with hw accel.

Migrated to a new nuc7i7 with intel iris graphics. Clean win 10 64bit install. And my cpu goes skyhigh in about 3-4 hours runtime.

Now disabled hw accel to see if this solves something.

All win10 updates installed so giess its the graphic card drivers. Any pointer which driver to use to resolve these issues?

I just disabled ha acceleration and cpu sames stable so thats what causing my cpu increase.

Run as service or as app wont make a difference.

However i still need ha accelleration to reduce cpu load, so what can i do?
