Info IDocs missing

Hi Experts,

I am working on BI 7.3. I got an issue in Process chain with Infopackage is getting failed with error message " Info IDocs are missing. The source system is not an SAP system. The IDocs are therefore created in the BW system. Since the IDocs are missing, a short dump probably occurred in the BW system".

As the Source system for this process chain is NON-SAP source system using DB connect and Infopackage is getting failed repetitively with above issue.

Could anyone please do let me know , how to rectify this issue ?

Thanks in advance.

Also please find the screenshot.
