Question regarding lease-limit - isc-dhcp 4.2.4-P1

[Philippe Maechler]

Hi List

How does the isc-dhcp 4.2.4-P1 behave if I set the lease limit to 0?

Is the zero for an infinite lease amount or will this restrict a client
from getting a lease?

A little bit of background information:
I have a class statement like this:

class "Customer_123"     {
  match if ( option agent.circuit-id = "00:0f:94:13:9e:3c" );
  spawn with option agent.circuit-id; lease limit 1;
  log ( info, concat ( "Class match: ", binary-to-ascii ( 16, 8, ":",
hardware), " matches Customer123" ) );
}


If I use a lease limit of 1, the server behaves like expected
It will hand out a lease to the first client requesting one and then log
the message below:
DHCPDISCOVER from 64:31:50:7a:1a:f8 via x.x.x.x: no available billing:
lease limit reached in all matching classes

If I set the lease limit to -1 i get a strange error message when
restarting the server:

Thanks all,
