OOM Killer kills my Intellij IDEA

barlog · 2020-06-15 19:16:34

Hi.

I have a desktop computer with 32Gb RAM.

❯ free -m
              total        used        free      shared  buff/cache   available
Mem:          32122       17122        2016       12002       12983        2552
Swap:             0           0           0

I use Intellij IDEA. It's a java IDE. It's memory usage limited to 4Gb.

But very often, almost always, IDEA killed by OOM-Killer and i don't understand why. With this log is used 2821588kB. Computer have much more.

Out of memory: Killed process 146214 (java) total-vm:16840132kB, anon-rss:2821588kB, file-rss:0kB, shmem-rss:108kB, UID:1000 pgtables:7404kB oom_score_adj:0

5.7.2-zen1-1-zen

Could anybody help me to find a problem please?

Ok. The problem was in IOMMU. I disabled it with kernel parameters iommu=off amd_iommu=off and in BIOS settings. And after this problem is gone.

total-vm:16840132kB

That number equals 16 GiB memory.
Maybe you told Intellij to use max 4 GiB per java VM instance instead of total memory ?

The zen kernel you're running makes many low level changes, did you try with stock kernel ?

As for disabling IOMMU :
Your post indicates your motherboard uses a X570 chipset, so you probably have an AMD processor .
Disabling IOMMU can have a severe impact on the performance of AMD systems using 64-bit software and cause hard-to-troubleshoot issues.

I've used AMD systems (Opteron and Threadripper processors, workstation / small server type motherboards ) for over a decade now.
Many of the advantages AMD has over competitors come from their use of IOMMU , NUMA and other design choices.

In my opinion an AMD system with IOMMU disabled is great for 32-bit OSes, but broken for 64-bit OS .
