Description

Klever fails without printing anything in its log (even in debug mode) in case of any errors related to control groups.
For example, memory swap accounting can be disabled, even if control groups are enabled, which leads to Klever fail. LDV Tools could detect such issues (and even work without swap accounting).

This is one of the most annoying errors that schedulers don't report properly (#6542).

As far as I remember work without swap accounting but with swap enabled can lead to hang ups especially with really high memory usage. I guess that this is the primary reason why BenchExec disables this. One can enable swap accounting (suitable for development) or disable swap (suitable for reliable experiments where much memory can be used).
