Just want to send a heads up.  Last night our system froze with the system
attention light on and SRC A600 0255.  This is a 720 running 4.4 with the
latest cume applied as well as all the group PTF's.  The SST logs showed
this to be a byte stream overrun on the IOP and lost contact with the
adapters it controls.  (Ethernet, Disk, Twinax - system console, and
communication lines.)  IBM rattled off many PTF's, all MF's.  The two we did
not have I recorded, MF27330 and MF26545.  These will require an IPL to
apply.  I recommend checking your systems and getting these PTF's on before
your system burps big.

As to attain the quality of OS400, not a single keystroke was lost.  The
system recovered before I could record the SRC's.  Every job resumed where
they left off.  What a beautiful system.
