[Kea-users] Fetching Active Leases

[Darren Ankney]

Hi Shobhith,

It is difficult to answer without seeing your Kea configuration.
Speculation would be that the lease is in memory and either not being
recorded to the file or was removed from the file somehow?  When using
'memfile' for lease storage, the leases are actually in memory.  The
file is only a record that Kea can use to read the leases back into
memory in the case it is restarted.  Its possible to setup memfile,
set a filename, and not have leases written to the file if you have
"persist": false in the lease-database configuration.

Thank you,

Darren Ankney
