We are about to start using the reserved lease functionality, and
bumped into this issue. I did not find any public CVS or patches for
this online, so I wrote my own while waiting. :-)
It stops the server from crashing, but I am not sure if it's a correct
fix. Could you have a look at the attached patch? (I have not tested
it in a Failover enviroment yet).
Is the next maint release far away?
We are setting the reserved flag through OMAPI by sending flags with a
char (1 byte) value set to 0x04. The support for this seems to be a
bit undocumented at the moment, will we get burned in the future for
doing this? :-)
I think the addition of the reserved lease feature to ISC DHCP is a
great thing! It makes the server more flexible, gives us less
management headache, and our customers get a better service. We plan
to use this to have dynamic and static allocation from the same pool.
