Hello,

I need some help in debugging this issue that I have. I am trying to retrieve a large file (2MB) from a vendor's server using SFTP with curl but it fails. I am able to pull a small file (247B). So, I know that I am specifying the correct information to log onto the server. I am not sure if it is a problem with curl or one of the other libraries.

I hope that I have included all of the necessary information.

Here is the command (removed id, password, and host info):
curl --trace /tmp/s -u id:passwd sftp://x.x.x.x/Usr/Out/t.txt --output t

Version:
curl 7.18.2 (sparc-sun-solaris2.10) libcurl/7.18.2 OpenSSL/0.9.8g zlib/1.2.3 libssh2/0.18
Protocols: tftp ftp telnet dict ldap http file https ftps scp sftp
Features: IPv6 Largefile NTLM SSL libz

Output from execution:
