- stunnel 4.33 service just crashes after some time.
- older stunnel versions do not crash
This looks like a bug in stunnel. Who do I contact because of this? How
do I contact him or her? Is more information needed, if so, which?

> - The windows eventlog shows:
> Event 7034, Service Control Manager
> The stunnel service terminated unexpectedly. It has done this 1 time(s).
