Dhcp on 2.2 stop responding

[nikkon]

Hi all,

Setup:
Internet -> WAN pfsense LAN -> sw -> ddwrt WIFI AP (dhcp forwarder) -> lan clients

I got some issues with the dhcp server for the lan interface.
pool : 192.168.100.15-50
the problem is that the dhcp server can allocate only several ip's then is not responding to any request.I got apipa ip on some clients and working ones from the scope on others.
If I manually allocate works just fine.
/var has 94% free space.

testing with a mobile device i have:

Feb 6 15:24:30 dhcpd: DHCPREQUEST for 192.168.100.15 (192.168.100.1) from c8:02:10:7f:dd:64 via igb1
Feb 6 15:24:30 dhcpd: DHCPACK on 192.168.100.15 to c8:02:10:7f:dd:64 via igb1
Feb 6 15:26:08 dhcpd: DHCPDISCOVER from a8:88:08:da:71:6c (iPad) via igb1
Feb 6 15:26:09 dhcpd: unexpected ICMP Echo Reply from 8.8.8.8
Feb 6 15:26:09 dhcpd: DHCPOFFER on 192.168.100.32 to a8:88:08:da:71:6c (iPad) via igb1

But device is still with no ip.

any clue?
