[ossec-list] Agent inactive status in ossec 2.7beta1

[PAL]

After a some issue in network ossec client lost connection to server. A 
message "Agent disconnected" was generated, client host mark as "inactive". 
It's good. But after network restore status did not return to "active", 
even ossec server got messages from client and generate alerts (I wait over 
two hours). After ossec server restart all statuses ok in few minutes.
