System selects optimal block size for a data set when we specify block size as zero while creating it.

NON SMS managed datasets will honour the BLKSIZE=0 if they are not opened and closed by the program

Is the file tape or DASD

If DASD - - -
Is the file SMS managed ?
If so, you need to talk to your storage people to take a look. The way that the ACS routines are set up may be part of the cause of the problem

If so - unfortunately this is site specific and can only be resolved by the people responsible for the ACS routines.
