CA loss package on 1 Hz rate

["Liyu, Andrei" <liyua@ornl.gov>]

Hi,

	SNS BLM system has 2 levels. First level is VME based/vxWorks
(IOC). Second level is PC/Windows (PC) - similar CAGateway. IOC sends
data one time per second to PC. Data is arrays (one array (720 floats)
per detector; up to 32 detectors per IOC). Array has information about
serial number of current package. PC checks serial number and prints on
terminal port if data was lost or come twice. Time to time (very seldom)
I read both problems.
	SNS works on 1 Hz now. IOC CPU loading ~ 3-5% and PC CPU loading
5%. On 60 Hz IOC will have 30% on 60 Hz. PC doesn't depend of
accelerator rate but depends from clients quantity.
	I hoped to use CAArchive to find source of problem. But I met
another problem. Archive lost connection to IOC when IOC/PC connection
was Ok.

	Does anyone see this problem? Any other suggestions to find the
source (IOC, network, PC)?

Thanks, Andrei.
