Experimental Physics and
Industrial Control System

Brad,

I don't know of any such vulnerability. Are you experiencing such crashes? 
If so please arrange for a vxWorks specialist to capture a stack trace,
thread 
cpu usage, MBUF usage information. With that information I could probably 
take the necessary steps to avoid trouble in the future.

I am particularly interested in situations where the IOC does not recover
after the sacan is completed.

Thanks,

Jeff
