An ABENDB14 has occurred. This might have been preceded by an ABENDD37. This would imply that the destination data set is too small. This reply is to warn the client of that possibility.
The FTP session ends.
Take action as is appropriate for the B14 and D37 abend codes. Verify with operations that a D37 did occur or try increasing the size of the PDS of the directory.
Verify that this is a recursive abend and take action as suggested by the abend that occurred.
