[clamav-users] TCP FIN Packet Received Before Data

After analyzing the pcap file I realized that NodeJs is sending the FIN
packet behind the scenes when it has finished streaming the data to the
socket. In an attempt to rule out any issues with clamav, I removed
streaming and read the entire file into a buffer in my service. When
writing the entire buffer at once, I was able to get clamav to respond with
the expected response consistently.

In other words, thanks for your help. Now that I know the issue isn't on
Clamav side, I'll take it from here. Thanks again for the help from the
community!!
