Environment

DX NetOps Virtual Network Assurance 23.3.1

Cause

The "/var" and "/var/log" mountpoints had the "noexec" flag active, causing certain executables not to run.

Resolution

To resolve this issue, the "noexec" flag was removed from the "/var" and "/var/log" mountpoints. This change enables the execution of binaries within these directories.
