Zabbix 2.0.6
I add 11 discovery rules and 11 hosts groups.

After add 3 groups in about 1-2h discovery get freeze. For example I can ping 10.100.83.0/24 subnet but it dont want to discover hosts.
Also host 10.100.80.127 is down, but discovery is showing that this host is working. So it looks like discovery get completly freeze... I wait about 6h and nothing change.
