Error description
ABN=0C4-00000011,C=R3600.710.IFC -CSQWTRC,M=CSQGFRCV,LOC=CSQWVCOL.CSQWVCOL+000007DE 0C4 abends in CSQWVCOL: these are linked to ERQE blocks that are created in CSQESEX for CF structure events, and then queued for structure tasks to be processed. In some conditions, the entire ERQE block is traced at the exit of CSQESEX. In this instance, CSQESEX was delayed after queueing the ERQE element, and the structure task had processed and freed it, causing the 0C4 when CSQESEX attempted to trace it.
