Hi,

I am using quickfix application to connect to an exchange and receive market data. The connectivity to exchange is through SSL and am using stunnel 4.15.
I see that stunnel dies, every time my quickfix application is restarted or sends a logout to server.
Please let me know if a solution is in place.

Below is the stunnel.conf file:
cert = /home/bhavna/workspace/stunnel/str10100str.pem
key = /home/bhavna/workspace/stunnel/str10100str.pem

; Some performance tunings
socket = l:TCP_NODELAY=1
socket = r:TCP_NODELAY=1

; Some debugging stuff useful for troubleshooting
debug = 7
output = /home/bhavna/workspace/stunnel/stunnel.log

pid = /home/bhavna/workspace/stunnel/stunnel.pid

; Use it for client mode
client = yes

; Service-level configuration

[currenex_stream]
;accept  = 127.0.0.1:1109
accept  = 1110
;prod details
connect = server_IP:port
TIMEOUTclose = 10

Below are the version details of stunnel:
