Comment 7 for bug 1956954

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 likely to have other unintended consequences.

My take here is: your setup needs tuning, and that's what those config knobs are for. Note that it's better to add a config file under /etc/sysctl.d rather than modifying the default /etc/sysctl.conf.

Let me know if this makes sense for you. I'm leaving this bug marked Incomplete for now.
