Hi all,
Thanks a ton for your kind attention for this issue.
rschroeder: Pt. 5 and Pt. 6 of your suggestions did the trick for me.So this is what I did.
1. The number of simultaneous downloads was set to 20 in the configuration(default is 10). I reduced that to 1. This ensures..that at a time there is only on config transfer taking place. This works perfectly fine for me. If we increase the number of simultaneous downloads, the NCM is not able to handle that I guess, beyond a certain point.
As you suggest it was 6 in your case.
2. I did the manual backup of the Running config of all the switches followed by the start up config:
Config -> Config Management -> Selected all the nodes -> Download -> Running Config/Start up Config.
All the config was downloaded successfully.
3. Thereafter I created a Job to download all these configs, and started the Job. The issue surfaced back again, showing random behavior. So I have a situation now where the manual download works but the job is failing.
4. I increased the timeout value to the maximum (max value was 14 min), and ran the job.It worked perfectly fine !!!!
Thanks for the help. Hope this helps others with the similar issue.
