<p><font face="monospace">Hi Jason,<br>
In HA, leases are synchronized each time a HA session is
established.<br>
Typically, when one of the HA partners has been restarted.<br>
This is governed by the "sync-lease" HA setting,which default to
"true."<br>
<br>
The "ha-sync" API command is used to synchronize the leases
between Kea servers.<br>

Does anyone know how often leases sync? We're using memfile to
store leases. The only thing I could find in the docs was
"synchronizing the lease database as needed".</div>

The leases between our HA pair are out of sync, and I'm curious
how often the primary sends the
<code>ha-sync</code> command to the secondary. Stork's Leases
Search feature is showing a valid IP lease for an address, but
it's only reporting that from the secondary unit. The lease was
allocated on 4/2 12:58 and expires today. I cleared the lease
from a javascript application at some point yesterday afternoon.
I figured the servers would've sync'd leases by now.</div>
