[Dnsmasq-discuss] dnsmasq forgets dns records

[Stefan Priebe - Profihost AG]

Hi,

i've a problem where dnsmasq seems to forget the DNS / hostnames.

Those devices affected are debian wheezy machines running dhclient.

Wenn they're freshly booted the .leases entry looks like this:

/var/lib/misc/dnsmasq.leases:1454145111 0c:c4:7a:3a:3f:d6 10.0.20.203
servername *

After some ours the entry looks like this:
/var/lib/misc/dnsmasq.leases:1454145111 0c:c4:7a:3a:3f:d6 10.0.20.203 *
*

The log entry is this one:
