This is what I see that indicates problems:

---

(rhq.core.pc.inventory.InventoryManager)- Got unknown resource: 11938

this means the inventory is not in sync between agent and server and is 
very bad. When agents get in sync, it usually means something really 
wrong happened - because the agent and server have handshaking between 
themselves to keep themselves in sync.

and you can see the sync handshaking failed here:

(rhq.core.pc.inventory.InventoryManager)- Failed to synchronize local 
inventory with Server inventory for Resource [11938] and its 
descendants: Can not connect http client invoker. 
org.hibernate.collection.PersistentMap. Response: OK/200.

Something really odd is happening - did you upgrade the server? change 
database endpoints? I can't think of how this could occur, but something 
out of the ordinary happened.
