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

Is it possible that one of your systems has run out of file descriptors? Because every socket is also a "file" in Unix and also occupies FDs. Just a wild guess anyway.

Have you checked the SSH log at the server side and does that give you any clues?
