Dear Ujwala
Whenever you want to provide IBM i message information, it would be better to give us the message ID. Luckily, a Google search gives me the information that this is most likely message CPA9001. When you encounter any IBM i error message, you should run DSPJOBLOG + enter + F10 and move the screen cursor to the message line of your interest and press F1 to see the full details of the message and I post it in the image below.

If you read the Recovery section of the message, you will see the solution to your situation there which is to respond to the message with "G". If you respond with G and still encounter any further error message. do what I described earlier again.
If you want to investigate SNADS before deleting the profile, I found the following commands suggested in another community :
Distributions can be queried using QRYDST --> OUTFILE
you can then receive the distributions using... RCVDST ... you could then idendify the sender...
DSPDSTLOG will show the (recent) history...
