In general, you are correct. But in this case it could have (or could be)
relevant.
FC is not in the range of WLM controlled DPs for z/OS 1.8 and above. Also
see the APAR I quoted in an earlier reply. What I didn't get from the first
post was if this just started happening or not.
Here is a table of DPs from the System Programmer's Guide to: Workload
Manager Redbook - SG24-6472-03:
Table 2-1 Dispatching priorities prior to z/OS 1.8
255 FF SYSTEM
254 FE SYSSTC
253 FD Small consumer
252-208 FC-D0 Dynamically-managed DPs
207-202 CF-CA Not used
201-192 C9-C0 Discretionary
191 BF Quiesce
Table 2-2 Dispatching priorities as of z/OS 1.8
255 FF SYSTEM
254 FE SYSSTC, SYSSTC1-5
253-249 FD-F9 Reserved
248 F8 Small consumer
247-203 F7-CB Dynamically-managed DPs
202 CA Not used
