OD reciever crashes only when using admin UI

System

Hi,
We are deploying content from OD 5.6 (No SP1) to OD 5.0.1, since long time. There is no problem using this as a command line or as a scheduled job everything is fine. But recently we introduced OD Admin UI(5.6 with SP1) to give user access to one specific deployment. Whenever we try to do this deployment the OD receiver crashes. Once we restart OD receiver it is deploying successfully through OD Admin UI. But all the scheduled deployments are working fine as before.

Appreciate any ideas/ help on this.

Thanks,
