When a NPC is created in region Moneyserver fail.

When avatar log in region the console money server show:
10:30:38 - [MONEY RPC]: handleClientLogon: Avatar Tomy Xue (fd44e9f5-d9bf-479b-ae95-89b66c2f2970) is logged on.
10:30:38 - [MONEY RPC]: handleClientLogon: Avatar Type is 0 and Avatar Class is 0

-------------------------
When npc is created console show:
10:32:54 - [MONEY RPC]: handleClientLogon: Avatar Unknown UserUPUUI (6e83fb12-b453-493c-9ea6-605cbfe236bb) is logged on.
10:32:54 - [MONEY RPC]: handleClientLogon: Avatar Type is 1 and Avatar Class is 1
10:32:54 - [MONEY RPC]: handleClientLogon: Server URL is empty. Avatar is a NPC?

From now nobody can upload pictures, mesh or pay some to other avatars.

I own some camping systems and fail when pay with this error showed in region console:
10:35:11 - [MONEY]: TransferMoney: No insufficient balance in client [283cb4c4-2084-43d2-9547-0bd02675b5cc]
Money server console do not say any. Fail silently.

Only restarting money server and region is solved.
Some idea about how to solve this?
