If you don't apply any change in your database so close some maps and try to launch GameServer again if same error so use another database, If work so use this query
PHP Code:
USE [SRO_VT_SHARD]
GO
UPDATE dbo.Tab_RefNest SET dwmaxtotalcount=3
then re-open (the closed) maps again .
- If your shard db got another name change SRO_VT_SHARD in query to ur shard db name .
