My hunch is that the Puppeteer instances (which are Chromium instances)
saturate the allocated memory limit for BPF, because they restart quite
a lot, so maybe each time a new instance starts, it makes BPF allocate
more memory, until it's full.
But I have no idea:
- how does JIT memory limit
Hi, glad to know it worked. There is some heuristics behind the default
bpf_jit_limit [1], it isn't a simple hardcoded value. We may discuss
bumping the default in Ubuntu, but I don't think that's a good idea: the
in-kernel heuristics has certainly been well thought, and just bumping
the number is
I confirmed the solution, it worked.
Also, I tried to submit the patch against the linux kernel (and/or
Seccomp-BPF subtree) following the official kernel guide
(https://www.kernel.org/doc/html/latest/process/submitting-patches.html)
but I couldn't even find the 33554432 value by doing:
git
If you want to change the value without rebooting that's:
sudo sysctl net.core.bpf_jit_limit=264241152
Add it to /etc/sysctl.conf if you want to set it automatically at boot,
but it's more meaningful to test as you said: wait for the issue to
happen and then change the value while the system
Dear Paride,
Thank you so much
I'll wait for the issue to resurface and *then* bump the value in order
to have conclusive evidence.
How should I do it?
echo "net.core.bpf_jit_limit = 262144000" >> /etc/sysctl.conf (as sudo)
Will that work without restart? Because the problem goes away
Hi Nino, I found a RedHat bug [1] that describes a similar situation
(affected is dhclient on ppc64le, but the error is the same).
The suggested workaround is setting
net.core.bpf_jit_limit = 262144000
via sysctl. I checked and on amd64 I find
net.core.bpf_jit_limit = 264241152
while on
Dear Lucas,
I've mentioned in the SO post that I linked that the nature of the issue
is intermittent.
I would be happy to provide additional logs next time I encounter the
issue.
Could you please advise on how do I collect additional logs?
Regards,
Nino

Thanks for taking the time to report this bug and trying to make Ubuntu
better.
I am not familiar with Puppeteer but since you think this might be
related to kernel, could you please provide any system logs so we can
understand what is happening? In a regular arm64 VM I am able to run
"apt update
