Venkat reported this issue today. Concurrent programs were erroring out with this message:
APP-FND-00092: Routine PRINT_OUTPUT cannot find the file $COMMON_TOP/admin/out/o65905566.out to print.
It turned out that someone had updated the profile option: Concurrent Report:Copies to 1. The value used to be 0.
Once the value was changed back to 0, the error stopped coming.
