Hi guys, I have been running stunnel in production for my email server users. It’s been great. It’s pretty stable, and does all that I ned to allow my users to connect to my ancient mailserver (EIMS) with modern SSL. In fact, it’s been so stable that until recently I had no backup on stunnel It just ran. Unfortunately, I have had some incidents where stunnel just crashes. When it does, it looks like my email facilities are completely down - not good. I now have a script that monitors stunnel, and when stunnel dies, the script re-starts it. Below is a snippet of my stunnel log at the crash point. Does anyone else have this problem? Are the developers interested in my data? I installed it as a pre-built binary package, and this is the most recent version in the packages collection, so I am reluctant to build my own stunnel. Thank you for a great tool. -dgl- 2026.02.06 15:04:25 LOG5[75312]: Connection closed: 784 byte(s) sent to TLS, 224 byte(s) sent to socket 2026.02.06 15:04:25 LOG5[75311]: Connection closed: 2036 byte(s) sent to TLS, 22 9 byte(s) sent to socket 2026.02.06 15:04:25 LOG5[75313]: Service [imaps] accepted connection from 107.12 3.20.177:6908 2026.02.06 15:04:25 LOG5[75314]: Service [imaps] accepted connection from 107.12 3.20.177:9568 2026.02.06 15:04:25 LOG5[75313]: s_connect: connected 71.39.101.34:143 2026.02.06 15:04:25 LOG5[75313]: Service [imaps] connected remote server from 71 .39.101.39:49527 2026.02.06 15:04:25 LOG5[75314]: s_connect: connected 71.39.101.34:143 2026.02.06 15:04:25 LOG5[75314]: Service [imaps] connected remote server from 71 .39.101.39:49526 2026.02.06 15:04:28 LOG3[per-minute]: OCSP: OCSP_check_validity: /usr/src/crypto /external/bsd/openssl/dist/crypto/ocsp/ocsp_cl.c:378: error:2707307D:OCSP routin es:OCSP_check_validity:status expired 2026.02.06 15:04:28 LOG4[per-minute]: OCSP: Unknown verification status INTERNAL ERROR: Memory allocated in a different thread at ocsp.c, line 412 2026.02.06 15:04:41 LOG5[ui]: stunnel 5.73 on x86_64--netbsd platform 2026.02.06 15:04:41 LOG5[ui]: Compiled/running with OpenSSL 1.1.1t 7 Feb 2023 2026.02.06 15:04:41 LOG5[ui]: Threading:PTHREAD Sockets:POLL,IPv6 TLS:ENGINE,OCS P,PSK,SNI Auth:LIBWRAP 2026.02.06 15:04:41 LOG5[ui]: Reading configuration from file /usr/pkg/etc/stunn el/stunnel.conf 2026.02.06 15:04:41 LOG5[ui]: UTF-8 byte order mark detected 2026.02.06 15:04:41 LOG5[ui]: OCSP: Connecting the AIA responder "http://status. rapidssl.com"
