This situation appears when a SIP message is sent in more than 4 "chunks" (this is tuneable). If the SIP message is too fragmented, OpenSIPS closes the connection to prevent packets fragmentation attacks.

Why opensips send TCP connection reset packet ?

I have been facing an error of

ERROR:proto_tls:tcp_handle_req: Made 4 read attempts but message is not complete yet - closing connection

while wireshark traces shows that a TCP connection reset packet was sent back to UAC by opensips server.
