Hi,

We are using stunnel to allow us to punchout to suppliers using TLS 1.2 protocol. We are seeing the following with this particular supplier.

2018.07.02 08:49:05 LOG6[4]: TLS connected: previous session reused
2018.07.02 08:49:05 LOG6[4]: TLSv1.2 ciphersuite: ECDHE-RSA-AES256-SHA384 (256-bit encryption)
2018.07.02 08:49:05 LOG7[4]: Compression: null, expansion: null
2018.07.02 08:49:15 LOG3[4]: SSL_read: Connection reset by peer (131)
2018.07.02 08:49:15 LOG5[4]: Connection reset: 1720 byte(s) sent to TLS, 0 byte(s) sent to socket
2018.07.02 08:49:15 LOG7[4]: linger (remote): Invalid argument (22)
2018.07.02 08:49:15 LOG7[4]: Remote descriptor (FD=13) closed
2018.07.02 08:49:15 LOG7[4]: Local descriptor (FD=3) closed
2018.07.02 08:49:15 LOG7[4]: Service [dell-https] finished (0 left)

We have set socket = l:SO_LINGER=1:60, but still occasionally have an issue.
Is there anything else that we may need to set?

Since the below is default, would not expect to set it..
socket = a:SO_REUSEADDR=no
        disable address reuse (enabled by default)



Best regards,

Dan
