Binaries built with a go version containing obsolete mlock kernel issue checks #64

Closed gyfis closed 3 years ago

Hi, I believe the (latest) v0.4.0 binaries were built with go v1.14.0 that contains old/imprecise checks for a specific kernel issue: https://github.com/golang/go/issues/37436

When we used the prebuilt binaries on a fresh Ubuntu 20.04 (kernel 5.4.0-65-generic), the binary crashed after a few minutes with the mlock issue described in the golang/go thread, even though the kernel is already patched for this issue. When we rebuilt the binaries from source with the latest go (go1.15.8), the crashes went away.

I think this can be mitigated by releasing a new version with a more recent go version, or compiling the source manually; I wanted to raise this in case someone else encounters this issue.

Thanks for the exporter!

0.4.2 is rebuilt with Go 1.15.8, hopefully that resolves your issue.
