Chad,
An omread error indicates that the ICC was unable to connect to the source
of the data, i.e., the block of interest.
This could happen for a lot of reasons (this list is not complete):
1) The CP is too busy to respond to the request for data
2) The CP lacks the resources to respond (there are all kinds of
resources)
3) There is too much broadcast traffic on your network and the open
request is getting dropped.
4) etc.
What type of CP is failing?
There are three types of uploads:
1) Block only
2) All blocks in a compound
3) All blocks in a station
Which upload type is failing?
Are you on FoxWatch? If so, have them test for Nodebus loading and
broadcasts in general. If you are not on FoxWatch, call your FS rep and
explain the situation and ask for an on-site analysis.
This is where I would start.

Subject: RE: save_all.sh update information
We have been having a problem uploading for the past year. We have not
successfully done an upload by hand through the ICC in that time. We have
a CAR out but as of yet have no help from Foxboro. The upload's fail at
random points in the process. The errors in the log file are an omread()
timeout, errors on various parameters and then the upload aborts. At first
we were told we could not do uploads with API running but stopping API and
trying did not resolve the problem. This is very frustrating because
everytime we change a PID the tuning parameters go back to initial unless we
change them by hand in the block. We would like to do automatic uploads and
savealls but cannot proceed until we can at least do them manually. Any
help would be greatly appreciated.
