This message is relevant to a CA gateway failure reported by Rolf Keitel (Mantis Entry 113). The symptom observed was a corrupt value written through the CA gateway when it is under a heavy client induced write through load. The bug has been isolated to the portable CA server. An incoming payload for a CA put was byte swapped twice when an IO operation was restarted due to heavy client loads.
I have committed a fix to CVS. This fix should appear first in
EPICS R3.14.7.
It will be important to *not* enable writes through your gateway until you receive a patch for this bug.
