Hello Ramesh, First part of the error is due to becuase u are on wondows I also get it but I just leave it it does not affect the problem however u are on 6.1, so I would rather recommend u to upgrade to 6.1.22. Secondly If u can give me more info about ur problem then may be I will have some ideas. For a break what u can do is u can run the same case on linux and check if get that and I am prety sure u will have safe landing. Podila
