Description

Some smart-proxy operations take considerable time. The free_ip call could take a very long time so 5 seconds is just not long enough

more than 5 seconds is not acceptable in terms of a web request.
in which scenarios does 5 seconds is too short? so far I didn't see such a problem....

Add a DHCP reservation for brslc025.brs.infineon.com/172.29.205.25
Failed to set the DHCP record: Request Timeout
Rolling back due to a problem: DHCP Settings for brslc025.brs.infineon.com 10 failed brslc025.brs.infineon.comsetDHCP

It may be possible that the DHCP timeout was due to my code being stopped in the debugger, (but I do not think that it was,) but the freeip was definitely a timeout.

What is the purpose of this timeout? It is so that the system does not lock up and need manual intervention. With this logic then a one minute timeout should be fine. Foreman should never timeout if there is any possibility whatsoever that the operation will complete. ("Slow" is not a bug or failure, though it does need some investigation.)

This slowness has been observed when running the native_ms DHCP proxy. Maybe the Windows box was being hammered when this operation took place. It is a virtual NT machine, and does not host the DHCP server itself, though they are both on the same site.
