Narrative:

4 flts; transiting south of vancouver's airspace at seattle's boundary; were the subject of multiple cpar failures. This required removing the active flight plan; then entering a new one. In every case; if the original route was re-entered; there would be another cpar error. This means the profile was corrupted; the flight was not being profiled correctly for conflicts. It was determined that some airspace reservations that would be active soon might have caused the problem. The airspaces were deactivated but the problem persisted. After a call was made to the tech center; a channel swap was performed. This alleviated the problems and the original rtes on all aircraft were re-inserted.
