BMC Discovery for z/OS - License Add On
Customer obtained abend U2000 in Discovery module MDZ0PR20 in their CAS. This occurred only once, CAS recovered and stayed up and running.
The abend occurs after 10 SRB probes have failed to complete. There was a recent change with PTF BPA1851 to allow a limited number discovery probes for swapped-out jobs. It appears this won't work for swapped-out jobs which have a Swapped Reason Code (SRC) of x'0A' (Unilateral Swap).

PROBLEM TITLE - ABEND U2000 IN MDZ0PR20
The abend can be avoided by setting the <dzs_max_swap> parameter to 0 in the MDZTTD00 parm member.
