A user is reporting sporadic failures with the log shown below. Any ideas on what could be causing this?

Sometimes the server has very old ssh libs, can cause some of these type of failures. Also look at SoSndBuf, and SoRecBuff, we set ours to 262144.
OOPS, the initializeSftp fails.
I guess you would have to use something like Filezilla or WinSCP to get that info.
Thanks. How does one check for old ssh libs? On the client? On the server?
on the server, This is Perl. right after initializeSftp
my $intVal = $self->getSSHVersion($ftp->lastErrorText());
getSSHVersion subroutine parses for text SshVersion returned by lastErrorText.
Thanks for the follow up.
