I assume you refer to:
capability: warning: `oneagentnetwork' uses 32-bit capabilities (legacy support in use)
This is a benign warning, which simply means that oneagentnetwork is using 32-bit Linux Capabilities. There is nothing to worry about, it will not harm performance / stability or anything else in any way.
Furthermore, in agent version 1.173 we've made improvements so that this warning should no longer appear. This version was recently released to SaaS customers and should be available for Managed deployment soon as well.
