Hi Lynn. This message appears to be the one causing your problem
C2P0572E Cannot allocate buffer; MEMLIMIT exceeded
That message has this explanation
The MEMLIMIT for the started task is insufficient for the specified size and number of in-storage buffers. The example MEMLIMIT specified in the started task procedures is 8G. Specifying 32 buffers of 256M matches a MEMLIMIT of 8G, but does not leave any space for other programs, like CKRCARLA, that also require storage that is counted towards MEMLIMIT.
