Abort Transaction Errors (6400s)

New writeups: 6401

6401 *    16           Cannot rollback %.*s - no transaction or savepoint of that name found.
6402      20           Inconsistency in rollback logic. ROLLBACK finds no matching SAVE TRANsaction or BEGIN TRANsaction. ROLLBACK aborted.
6403      20           No matching savexact record found when rolling back the subordinate transaction %.*s.
6404      18           Process %d in database '%.*s' was aborted. The transaction was rolled back, but an ENDXACT record was not written, probably because the log is full.
