Ram Usage of karabiner_observer and karabiner_grabber ramping over time

[ollidiemaus]

I have the issue that my karabiner_observer and karabiner_grabber are increasing in ram usage over time. It doesn't seem to flushed unless I restart the app. I use karabiner 14.10.0 and macos 13.1 on a Macbook Air M1

[ollidiemaus]

This issue persists with 14.11.0

[keyworks]

Same here. I'm noticing karabiner_observer sometimes slows my computer to a halt as it uses over a 1GB of memory so I have to kill it every once in a while.

I'm on Karabiner 14.11.0, Mac OS 13.1, Macbook Pro Intel

[lundstrj]

I discovered that my karabiner_observer was using some 860Mb of memory (searching lead me here) I am on 14.12.0 on MacOS 13.2.1 (22D68) Macbook Pro M1

[nealeyoung]

Having the same issue with karabiner_observer.
I am on latest (I think) on MacOS 13.4 (22F66) Mac Mini M1.

Karabiner observer is using 1.62 GB of physical memory. mac M1 Sonoma V14

This app consumse Memory So much ! 3.5G? too much.. and there are many processes. It seems that a minimum version that selectively turns off the opt out function is needed.

+1. This issue needs some attention. Machine: M1 macbook air, OS version: Sonoma

[lucasvabrantes]

Same here, folks! Sometimes it slows down my Macbook Air M1.

[matheusamazonas]

The karabiner_observer process is currently taking 927 MB on my MacBook Pro M1 Max, running macOS Sonoma 14.2.1.

[sbaildon]

Activity Monitor overview reports questionably high memory usage;

But double-clicking the process reveals entirely different numbers

[wuhh-wuhh]

Same issue. MacOS 14.1. Karabiner 14.13.0

RAM usage at 1.02GB. Virtual memory at 390GB

[jsimonlane]

Seeing this as well, M2 Macbook Pro, Karabiner 14.13.0

---

The below hack acted as a workaround for me.

➜  $ sudo launchctl bootout system /Library/LaunchDaemons/org.pqrs.karabiner.karabiner_observer.plist   
➜ $ sudo launchctl bootstrap system /Library/LaunchDaemons/org.pqrs.karabiner.karabiner_observer.plist

I realized the memory usage increases according the last time you have rebooted your device. So, for now, to hold on this bug, i just reboot my macbook and the karabiner_observer starts again with low memory usage.

Of course, you can kill the process on activity monitor, but i like to reboot.

[angryPodo]

I've also experienced the same issue. I'm using a MacBook Air with macOS 14.4.1 Sonoma. I've confirmed that the memory decreases upon reboot, but it increases proportionally over time.

[beyond2001]

I've had the same issue. I am using Karabiner 14.13.0 on Macbook Pro m1 with macOS sonoma 14.5. The memory usage increases proportionally over time.

[braendi]

Same here. MacBook Pro M1, macOS Sonoma 14.5, Karabiner 14.13.0.

Ram usage: 2.17 GB System: macbook Pro 16, M1 Pro 2021 OS: Sonoma 14.5 apps updated

Seems like some changes are coming (currently in beta):

• Integrated karabiner_observer functions into karabiner_grabber, and then karabiner_observer has been removed.
• The number of background processes has been reduced, resolving performance issues caused by inter-process communication that were occurring in some environments.

Just installed the beta and karabiner processes are using MUCH less memory.

[kuba2kopec]

I've had the same issue, just installed the beta version and will monitor the RAM usage

[velaia]

RAM usage after 2 days with the beta version seems stable (at least not going into the 100s of MB). If this holds true for other users and when the beta becomes stable, this issue could be closed.

[Gautham]

Thank you for the work, Tekezo 🙇 Can the beta be released soon? My company's infosec doesn't allow me to run the beta version :(

[matheusamazonas]

Version 15.0.0 is out and it seems to have fixed the problem for me. 👏

[beyond2001]

it's only been out for a couple of days, use a few days to see if it fixes. My memory usage still grows fast

I have been using it for a a couple of days and memory usage did not grow. I didn't just install and celebrate it.

[velaia]

Update on version 14.99.8 after running it for 3 weeks. _karabinergrabber still seems to accumulate memory over time.

If I'm not mistaken, the version that supposedly fixes the bug is 15.0.0, which was released about 3 days ago. Have you tried that one yet?

2 days is still too short to verify this fix.

I've had the same issue. I am using Karabiner 14.13.0 on Macbook Pro m1 with macOS sonoma 14.5. The memory usage increases proportionally over time.

I am still having the same problem on 15.0.0

[velaia]

Same here. The karabiner_grabber process seems to grab more and more memory over time. This is verison 15.0.0 running for at about a week. The memory usage has grown from less than 50 MB to over 200 now.

[dr-itz]

15 days, 17.12 GB. Yes GB
