ssh_exchange_identification: Connection closed by remote host Connection closed

Hi Everyone,
Good day.

Scenario:
2 unix servers -- A (SunOS) and B (AIX)
I have an ftp script to sftp 30 files from A to B which happen almost instantaneously i.e 30 sftp's happen at the same time.
Some of these sftp's fail with the following error:

ssh_exchange_identification: Connection closed by remote host
Connection closed


Its not the same files everyday which give me this sort of trouble.

Could you please provide your insights to solve this.


Thanks,
G1

NAME
sftp-server - SFTP server subsystem SYNOPSIS
/usr/lib/ssh/sftp-server [-f log_facility] [-l log_level] DESCRIPTION
sftp-server implements the server side of the SSH File Transfer Protocol as defined in the IETF draft-ietf-secsh-filexfer. sftp-server is a subsystem for sshd(1M) and must not be run directly. Command-line flags to sftp-server should be specified in the Subsys- tem declaration. See sshd_config(4) for more information. To enable the sftp-server subsystem for sshd add the following to /etc/ssh/sshd_config: Subsystem sftp /usr/lib/ssh/sftp-server See sshd_config(4) for a description of the format and contents of that file. There is no relationship between the protocol used by sftp-server and the FTP protocol (RFC 959) provided by in.ftpd. OPTIONS
Valid options are listed below. As stated above, these are to be specified in the Subsystem declation of sshd_config. -f log_facility Specifies the facility code that is used when logging messages from sftp-server. The possible values are: DAEMON, USER, AUTH, LOCAL0, LOCAL1, LOCAL2, LOCAL3, LOCAL4, LOCAL5, LOCAL6, LOCAL7. The default is AUTH. -l log_level Specifies which messages will be logged by sftp-server. The possible values are: QUIET, FATAL, ERROR, INFO, VERBOSE, DEBUG, DEBUG1, DEBUG2, and DEBUG3. INFO and VERBOSE log transactions that sftp-server performs on behalf of the client. DEBUG and DEBUG1 are equiva- lent. DEBUG2 and DEBUG3 each specify higher levels of debugging output. The default is ERROR. EXIT STATUS
The following exit values are returned: 0 Successful completion. >0 An error occurred. FILES
