SAP SFTP Sender Channel is not Polling.

Hi All,

Need help on the below issue.

Its a file-file scenario with simple AS_IS transfer. The files are present in the given location and i have started the sender Communication Channel in RWB.

But the issue is the SAP SFTP sender Channel is not polling from 6 days.

I have tried creating another channel( copy of the original one).. then the new channel started polling but then after sometime the new channel also stopped polling.

checked for the locks in NWA, but could not find any locks on SAP SFTP adapter.

Quick response will be highly appropriated.

Thanks

Anjani
