Server DHCP3 has stopped to give addresses

[aigore]

Hi all, I'm writing because my ubuntu server has started with troubles .
It's running Linux 2.6.32-29-generic-pae kernel for ubuntu server 10.04 and after the last update it stopped from giving addresses on clients connected.
Dhcp3 server it's running and the conf files are fine, but i can only use static addresses assignation now...
Also MYSQL has stopped working (installed for Bacula purpose) but now the dhcp problem is the biggest issue. I work in an office where dhcp is fundamental, too much clients (about 15) that are personal laptops also (so static assignation for clients is not a good choose).
Please any one could help me? It's two days I'm trying to figure it out without success.
also tried removing and reinstalling dhcp3-serer...no way.
Here are my conf files

Another strange behaviour is that my shell doesn't keep the command history.....mmmmm....weird

Thank you in advance!

Check /var/log/syslog after restarting dhcp. Usually there is something explanatory about why no leases were given.
