MVS 3.8j (TK5) Crashes on Massive SORT


 

I've been playing with a SORT job to stress test my system.? It sorts 99,999,999 random 80 byte records.? The job works just fine if I am running with 1 CPU.? Run MVS with 2 CPUs and it typically locks up, clocks, and sometimes I have to clear SYS1.LOGREC after an IPL.
?
As far as I have read, MVS 3.8j ought to work fine with 2 CPUs but I've verified this enough to know that I can reliably reproduce the issue.
?
If anyone has any ideas and would like me to produce some debug data to sift through, please let me know.? In the meantime, I'll run MVS with 1 CPU.
