Unable to create new pooled resource in Communication channel

Hi All,

We are working on FTPS scenario with FTPS on receiver side.

When I am trying to post message I am getting error as

Message processing failed. Cause: com.sap.aii.af.ra.ms.api.RecoverableException: Error when getting an FTP connection from connection pool: com.sap.aii.af.service.util.concurrent.ResourcePoolException: Unable to create new pooled resource: java.lang.NullPointerException

Can anyone please help me what is the reason for this error?

Thanks in advance

Best Regards,
