andrijapanicsb opened a new pull request #3662: Increase lease time to infinite
URL: https://github.com/apache/cloudstack/pull/3662
 
 
   Lease time set to effectively infinite (36000+ days) since we fully control 
VM lifecycle via CloudStack.
   Infinite time helps avoid some edge cases which could cause DHCPNAK being 
sent to VMs since
   (RHEL) system lose routes when they receive DHCPNAK.
   When VM is expunged, its active lease and DHCP/DNS config is properly 
removed (#3627 and #3608) from related files in VR, so the infinite duration of 
lease does not cause any issues or garbage.
   There will be soon a PR which also regenerates the 
/var/lib/misc/dnsmasq.leases (active lease DB file) in the new VR (when 
restarting network with cleanup), which will help around RHEL edge cases 
(described above) for the VMs who are already running in productions systems 
with 30d lease time.
