Sending request message to SQL server

Here we have done a small Orchestration program in which second orchestration is getting called from first one.In second orchestration we have use SQL adapter for inserting data into database & sending parameter to Stored procedure in SQL Adapter from first orchestration. We are able to call second orchestration correcly from first one but error occur at the request message of SQL adapter as

[b:073c131618]\”SQL\” adapter is suspending an outbound message going to destination URL:\”SQL://AESERVER/kinkosii/\”. Details:\”Unknown Error Description \”. [/b:073c131618]
