cpu nearly at 100%

[kobold81]

Hi,

today I made a apt-get update and upgrade of my debian buster system.
Before, zoneminder 1.32 ran fast and the windows to my 3 cameras opened fast as a lightning.

After the upgrade it was slow as hell and the monitors are unusable. the commadn TOP shows nearly a combined 100% for the zoneminder processes.

I did an update to 1.34 but the same problem persists. What could be a solution please?

Are you running on a Pi?

No, 16gb xeon 3ghz server.

Are you using the zmrepo?

I have not done an upgrade on Buster but have 1.34.0 running on a pi 3b+ and 1.34.2 on an i5 quad core with 8 GB RAM.

It is possible that the database did not fully upgrade.

You say 100% for the zm process. Which zm process? There are many, each with a different job.

I apologize for the delay.

Using the command TOP, there are 3 processes when I open the preview of a single camera
44 - 53 zmc
37 zmc
40-50 nph-zms

What I did:
- installed adminer and removed all logs (quite a lot)
- reapplied the database structure

and it works again...

I used "zmrepo.zoneminder.com/debian/master buster/" but have now updated the package.

Top shows 37% zmc and 36% nph-zms

Now cam 1 has a small 1/5th of the image with pixel errors, cam#2 (which is an exact copy of #1) is full of pixel errors.

-> the pixel errors seem to stem from zoneminder, because vlc shows a perfekt picture...
a higher image buffer than 51 is actually worse that keeping at 51 or 20 and igrnoring the warning message...

Look in your logs, we can't guess.

Are your Max FPS and Alarm Max FPS clear? Are you using TCP or UDP?
