[stunnel-users] Strange Stunnel crash (no errors, issues, anything)

Long time lurker, new poster though!
I've got two servers running Stunnel v2.54 (yet to upgrade as I've been
waiting for an x-forwardfor patch to become available). I noticed recently
that one Stunnel nodes had exited, requiring a restart. I'm not sure if
it's a co-incidence, but I've only just changed the cert on both installs
This, of course, is very concerning as it's only just become a problem, but
being the core SSL endpoint, it knocks our server offline until it's
Now comes the interesting bit, I've run the SSL Labs SSL Health check at
https://www.ssllabs.com/ssltest/ just to see if anything comes out of it,
and noticed that without fail every time it runs (and the first server is
online) it'll know Stunnel offline as it goes through it's tests:
*"Testing TLS v1.0...."
"Testing TLS v1.2...."*
*-- SERVER OFFLINE --*
This was noticed by a fluke, but appears to happen every time I restart and
then rerun the test.
I'm not getting any segfaults, or errors from stunnel, and it only affects
the one (primary) server. Can anyone shed any light as to what might be
causing it, how I can get any more info out of stunnel, or better yet, fix
