Joseph, The example address you posted looks very much like LSQA to me - are you sure it was returned by VSMLIST SP=PVT ?
Also - did you check the return code from VSMLOC? Might be worth capturing a in-flight dump of the target address space and comparing what you are seeing with IPCS VSMDATA.

Note: 1. The number of subpools in the private area is a 31-bit number. 2. The address of the TCB is contained in a fullword. 3. Figure 37 on page 218 shows the format of the allocated storage information for the subpools owned by each TCB. The storage information begins at offset 0, "number of subpools" in that figure. 4. If you specify SPACE=FREE, free space information follows each allocated block descriptor. Figure 42 on page 221 describes the format of the free space information.
