This message indicates that based on the current average key compression of the sequence set, the sequence set records could not hold keys for all of the data CIs in a data CA.
The average key length is used to determine how many keys can be in a sequence set record, but some sequence set records may have better or worse key compression than the average. Thus the number shown should be considered an approximation and not an exact number.
