Increasing usage of RAM memory

[mendozaLt]

I had to say it

Recent update, and i am having this:

And it takes 6 minutes after restart to go back to 98% used memory...

Been waiting for a solution for long time ... but for now i just had to stop zoneminder, as i cant use it normally...

Have you tried to set "Maximum Image Buffer Size (frames)" to some value instead of 0? Actually the meaning and effect of this parameter is not quite clear to me, but setting this to 1000 (for exampe) may solve the problem. Anyway in "Buffers" menu you'll get the definite max "Estimated Ram Use" instead of "Unlimited".

I tried, this is after setting it to 500 (remember, server has 56 Gb in total, and ZoneMinder takes 43 of it...):

MaxImageBuffer should be roughly 2*keyframe interval. It should only be larger to deal with slow writing to disk or other temporary slowdown. So 500 is likely too high unless your stream is h264+ (very high keyframe interval).

If it is set too low, ZM will drop packets and complain.

I see... how can i know what keyframe interval is? I don't know much about it, but Isn't it like 2 or something?

Might be in your camera settings menu.

I set it to 50, for all cameras, that does not give any positive result...

did you find a solution?

Can anyone explain how it is possible? Why do I have duplicated monitors 69 using 8Gb of memory in S sleep state? It's just simple monitor with motion detection 12fps 4k. Recently I have low memory problems, sometimes, maybe after update, I'm not sure. Can't see any noticeable errors I will increase log.
Or maybe I should try 37 version...
Or it's just normal?, I added 16gb, who knows, maybe it will help. So memory hungry)

i am def getting high memory usage.. it could just the cpu cant keep up with the frames so it just keeps adding buffer until it runs out of ram and then the zmc crashes and starts over.

i set cron timer to reboot zm every few hours and it keeps the memory usage lower. if you let it run continuously it will eventually fill up the swap file and crash the server.

my pc is a 3900x with 80gb of ram and 10 IP cameras, most of 5MP but a few are 8MP.
most of the camera buffers are set to 4gb a couple of the 4k ones i had to go higher to keep the warnings about the buffer being too small.

the pc is averaging around 40-60gb used ram.

Not sure if this will help. I created a cron job that watches the memory zmc uses and restarts zoneminder if it passes the setpoint I determine. Of course you will need to tweek it for your system. I placed this under the cron.houly folder in etc.


#!/bin/bash
lf="/var/log/restartzm.log"
tmp1="$(ps -C zmc -o pid,comm,pmem)"
echo -e "$(date '+%Y-%m-%d %H:%M:%S')\n $tmp1" >> $lf

zmch=$(echo "$tmp1" | awk /zmc/'{if (max == "") max=$3 ; else if ($3 > max) max=$3}END{printf "%d", max}')

setpoint=30

if [ $zmch -gt $setpoint ]; then
echo -e "$(date '+%Y-%m-%d %H:%M:%S') - $zmch is greater than the setpoint of $setpoint" >> $lf
echo "Restarting Zoneminder" >> $lf
/usr/bin/systemctl restart zoneminder
else
echo -e "$(date '+%Y-%m-%d %H:%M:%S') - $zmch is not greater than the setpoint of $setpoint" >> $lf
fi
