Dear Andrew,

This problem is becoming critical.  Every vxWorks/PowerPC IOC at the
NSLS at Brookhaven is crashing within minutes if it is connected to the
NSLS network.  The only way the beamlines can run is to disconnect their
switches from the NSLS network.  Tim Mooney told me yesterday that
several CATs are now seeing this problem here as well.  It is not known
if the network activity that is crashing the IOCs is a malicious or not.
Finding the source of the packets at the NSLS is being worked on, but
the real solution is to see if there is a fix for the network software
on vxWorks to make it immune to this problem.  Can you see if Wind River
has a patch that fixes this?

Thanks,
Mark
