Server error on application Sales Orders for Iphone

Hi Experts,

I'm having a error when i try to consult a Sales Order in my Iphone's app. The error says: 'Server error: contact your administrator'. On SCC log's i have this record:

2014-01-17 10:21:15.949 INFO MMS TmHttpclientPool-315 [com.sybase.sup.server.http.TmApplicationHandler]On connection expired .....

I have configured the Application Connection Template and Connection Pool with same Application Endpoint as prints attachments.

Anyone have any idea to fix this error? I'm missing some config. at SCC?

Thanks and Regards!
