English to Italian Tech/Engineering Manufacturing line-down situation

Salve a tutti! Si descrive il ruolo del priority shopping cart nel sistema SRM SAP:
"Designed for non-emergency, business-critical needs, Use only in exceptional circumstances
Prioritized for processing
Should be used for business-critical needs processed within the standard cycle time
Examples:
Revenue at risk
*Line down situation*
Executive directives
Tracked and reported to prevent abuse"

Mi pare di capire che line-down si riferisce a situazioni in cui la produzione si ferma...
Grazie mille!
