I am not sure about the S878. However depending on the level of z/OS you are running, there is a parm called CHECKREGIONLOSS which can help alleviate some S878 abends. You may wish to check it out. You might also rule out the QSAM issue but coding Buffers on the DUMMY statement and see if that helps.
And from the JCL Reference Guide value=0M or 0K A value equal to 0K or 0M -- gives the step all the storage available below the 2 GB bar. This includes below and above 16 megabytes. The resulting size of the region below and above 16 megabytes depends on system options and what system software is installed. When REGION=0K/0M is specified, the MEMLIMIT value is set to NOLIMIT. Note: This may cause storage problems.
