Interesting.... They're dated three days LATER than the date we
installed the latest ucode (that was supposed to fix the problem).
We enabled SEGMENTATIONOFFLOAD on the sandbox (z/OS 1.9) yesterday, but
there's very little TCPIP load on the sandbox (still doing IVP of 1.9,
and post-installation "cleanup"). Maybe we can cobble up something that
should "stress" it to the breaking point (maybe FTP-ing some SMF offload
datasets or sysdumps?).
Meanwhile, we'll leave it disabled on the other LPARs until we hear
something more reassuring (or determine that we can't "break" it on the
sandbox).
