strange net::SFTP Perl module debug entry

I installed Net::sftp on a solaris 8 server and I am able to successfully transfer files to the remote server. I am running the command out of a script with debug=1 on so I can see the verbose output.

The last two lines of the debug output show it couldn't fsetstat, but I don't know what that means. The files seems to transfer. These are the last few lines.

Any idea what it means?

hccssun5: sftp: Sent SSH2_FXP_OPEN I:4 P:SftpTestfile
hccssun5: sftp: Sent message SSH2_FXP_WRITE I:5 O:0
hccssun5: sftp: In write loop, got 56 offset 0
hccssun5: sftp: Sent message T:10 I:6
Couldn't fsetstat: Failure at ./TestSFTP line 17
hccssun5: sftp: Sent message T:4 I:7

fsetstat refers to setting the file permissions. What are the permissions of the local file, and what are they on the remote file?

The local and remote file permissions are 644. The permissions on the directory where the files are stored is 700.

Thanks
