Interface trip stop and workflow purge

Hi All,
interface trip stop often completes with warning and deliveries are stuck in the interface.

Analyst says this may be because of workflow purges before interfacing.

I have checked in the system and no one has submitted 'Purge Order Management Workflow' concurrent request and neither it has been scheduled.

however “Purge Obsolete Workflow Runtime Data” concurrent request scheduled twice a day with below parameters

(1) , , 7, TEMP, N, 500, N
(2) , , 30, PERM, Y, 500, N

can above scheduled concurrent request be the reason for my workflow purging and stuck deliveries in interface?

Please advise.

Thanks
