[ldrolez]

Hi! Did you find a solution? I got this issue after a Docker upgrade

[vladaman]

@ldrolez we moved it to a different VPS instance. The VPS provider we were using was running distro / kernel / virtualization which did not provide information about maximum available memory.

[ldrolez]

ok I disabled the KNN plugin to be able to start ES

[grownuphacker]

I posted my findings on another issue:
