OT - sftp

[scooter6 at gmail.com]

We've had several night time scripts that use SFTP to send files to
overnight
All has worked fine until this morning - I get email confirmations and they
all had
"Couldn't read packet: Connection reset by peer"

So I tried to manually connect and got the same thing.
I then used FileZilla on my PC and connected without issue to one of my
vendors who we use username/password with - no keys involved

So I called him - he can see me login from FileZilla and from my server -
but when connecting from my server is shows I immediately logout too....

Again, this has been working for years up until last night - I have not
installed any other packages, did a full server reboot, don't see any
errors in log files, etc.

Any idea what would be causing this?  I double checked permissions and
don't see anything that's glaring...
I can't even sftp to localhost...I get the same thing....
I removed localhost from known_hosts in ~/.ssh directory
then   sftp localhost     I get the standard 'The authenticity of localhost
can't be established blah blah blah....Are you sure you want to continue
connecting?  I type yes and get the same
Can't read packet: Connection reset by peer....
But I do get our standard FTP disclaimer so I know it's "connecting' after
I put 'yes'
It also re-adds the localhost to known_hosts file - so that helped me
confirm it doesn't appear to be permissions....???

Really baffled here.....out of ideas where to look.....

Any one run across this before?

Thanks
Scott
