Could not Parse channel erro

Hi XI experts,

I am Very New to XI and i am facing an issue with file adapter. I have done all the steps perfectly ,but when i check cache i am able to see an error 'Could not parse channel file_rec'.This is showing when Cache update.

From that i am thinking it may be because file adapter is not configured properly in IS,but not sure.

Please help me to resolve the issue.

Thanks and Regards

J.
