Interesting, I didn’t know that! Wikipedia says “A launch attempt two days earlier was scrubbed because of a timing problem in one of Columbia’s general-purpose computers.” and NASA says “Launch April 10 postponed due to timing skew in orbiter’s general purpose computer system. Backup flight software failed to synchronize with primary avionics software system.”, but this article explains the problem in extreme detail.
