Sybase SQL Error Message
Database segment ‘%2’ is not valid. %3 imaginary freelist blocks were found, but %4 imaginary freelist blocks were expected. This segment cannot be used. %1
Reason for this Error
When a database segment is opened, the segment header is read and the number of freelist blocks read from the header is compared with the number of freelist blocks that are expected to be read from the segment header. If the numbers do not match, the segment cannot be used and the database must be restored from backup.
