--- Comment #11 from Andrew Colin Kissa <andrew@???> ---
I am seeing an issue when i run the tests against the server script that there
are intermittent cases where the server is closing the connection too early.
When i use the AV endpoint itself i cannot pickup these issues. I have double
checked my code and cannot pick up and issue that could cause this.
Take this example dump, the server side issued the FIN before even sending
the verdict. Why would the server want to end the connection before sending the
">DETECT EICAR-Test-File" line. This is for the second test.
