If you use streaming replication without file-based continuous archiving,
you have to set wal_keep_segments in the master to a value high enough to
ensure that old WAL segments are not recycled too early, while the standby
might still need them to catch up. If the standby falls behind too much, it
needs to be reinitialized from a new base backup. If you set up a WAL
archive that's accessible from the standby, wal_keep_segments is not
required as the standby can always use the archive to catch up.

Basically you did just that when you destroyed the archive. Apparently the
master doesn't churn through WAL quickly enough to have had to discard the
segments from the prior two hours.
