I am using Jetbrains Rider IDE for development but after kernel upgrade (from v5.3.0-45 to v5.3.0.46) it started to freezing for a few seconds in my every action like scroll up and down or when I try to write some code.

Today I also tried the v5.0.3-51 but the result is still the same. Because of this issue I have to use kernel v5.3.0-45.

Only my IDE has this issue and the other applications work well. Here is a cpu history screenshot while my IDE was freezing.

I guess there is a problem between the JVM(Rider uses JVM) and the CPU.

System Informations

Note: The problem started to appear after I upgraded my system on 12.04.2020 and 13.04.2020. Here is the upgrade history related to that time.

Note: If your question is correctly typed, it looks like you're running with an old 5.0.3 kernel on Ubuntu 19.10. Why? You should be running kernel 5.3.0.

Even though you have 16G RAM, I think that your 1G /swapfile is too small. Let's enlarge it...

Note: Incorrect use of the dd command can cause data loss. Suggest copy/paste.

sudo swapoff -a           # turn off swap
sudo rm -i /swapfile      # remove old /swapfile

sudo dd if=/dev/zero of=/swapfile bs=1M count=4096

sudo chmod 600 /swapfile  # set proper file protections
sudo mkswap /swapfile     # init /swapfile
sudo swapon /swapfile     # turn on swap
free -h                   # confirm 16G RAM and 4G swap

This line should already be in your /etc/fstab...

/swapfile    none    swap    sw      0   0

Then reboot the system to confirm proper operation.

  • Oh sorry about that. My kernel version is 5.3.0-51-generic. I have edited my question. I will try to expand my swap space and let you know about it. But during the freezing time ram is looking stable, only my CPU is going down. I got some software upgrade on 2020-04-12 and then this problem appeared. If swap expanding doesn't help I will share my package upgrade history.

  • Unfortunately, to expand the swap space is not helping the problem. I updated my question and added my upgrade history. I am suspecting upgrades that installed in 12 and 13 April.

  • @Goker What version Jetbrains Rider IDE? Current is 2020.1.1 from April 28, 2020. Current JVM?

  • @Goker check for a software update and see if the -51 kernel is available to you yet. I seemed to have some problem with -46 that -51 seemed to fix. Did you upgrade your Jetbrains Rider IDE?

  • Yes I did, everything is up-to-date. I guess something broke in kernel version -46 and still continuing. Fortunately, I am able to use the IDE properly when I reboot my system with kernel version -45.
