This seems to refer to a version of Yocto, and ptest is some kind of
package test?

This means that something (presumably caused by your ptest) to invoke
sshd in a way that did not involve a TCP connection (eg running sshd
-i) then immediately disconnecting.

This is more or less the same, with the difference being that whatever
it was sent an empty initial protocol identifier (probably a newline).
If your tests are invoking sshd to test it, they should probably use -e
to write its logs to stderr or -E to write it to a file rather than
letting it write to syslog.
