File Adapetr: File is not picking from File directory

Hello,

Issue: we are facing issue with file sender adapter like file is not picking from source file directory.

Scenario: FTP1 >PI >FTP2

1. SAP PI sender communication channel will pick the file from FTP1 and process to PI file server (NFS)

2. from PI file server (NFS), file will process again to FTP2

So while picking the file, it shows following error:

-

Could not process due to error: java.lang.IllegalStateException: Error during RETR epilogue: com.sap.aii.adapter.file.ftp.FTPEx: 451 Transfer aborted. Broken pipe

Conversion of file content to XML failed at position 0: sun.io.MalformedInputException

Processing started

-

this issue occur after we migrate the PI server from hpunix to aixunix.

Best Regards,SARAN
