After processing the FTP.DATA file, the server cross checked the new values of the RECFM, LRECL, and BLOCKSIZE parameters and found the RECFM parameter set to a record format which requires the BLOCKSIZE to be at least four greater than the LRECL parameter, but it was not. The server attempted to change the BLOCKSIZE value to LRECL + 4, but the LRECL value was greater than 32756, which would cause the BLOCKSIZE to exceed the maximum value of 32760. LRECL was changed to the indicated value.
