I checked the 'omnirc' file for any local environment variables that might affect this, and found none. Then, I checked the 'global' file, and the only thing I found that even came close was
# MinDelayForConnectionRetry=TimeInSeconds
# default: 30
You can increase this value to 60 seconds, but, all if may do is to increase the time it takes top produce the original error
Edit the 'global' file, find the line
# MinDelayForConnectionRetry=TimeInSeconds
Make a copy, edit one of the lines to remove teh # sign and teh 'space' that follows, and set teh value to 60
MinDelayForConnectionRetry=60
# MinDelayForConnectionRetry=TimeInSeconds
Save the file, stop and restart Data Protector, and run your IDB backup. if this is of no help, you will need to open a case with the response center, and run 'inet' debugs on the client system 'saturn.local.net'
