BizTalk Party Configuration Batches (Resume button enabled) - Batch splitting failed

Hi Experts,

We have an application which splits incoming EDI using BizTalk EDI Application. Splitting based on Party Configuration under Batches tab. This application was working fine till a week ago, when files were not generated anymore. We found that there was 'Resume' button activated in the batches tab. When pressed 'Resume' then instance of Microsoft.BizTalk.Edi.BatchingOrchestration.BatchingService started but it remained active for a long time, and then we had to terminate it.However no batches appeared in outbound folders.

Please help me understand the root cause of this issue and what can be done to remove it. 

Thanks in Advance.
