This error showed up in my apache error log!

[ssl:info] [pid 74929] (70014)End of file found: [client ...] AH01992: SSL library error 1 reading data

I found issue #18866 - looks like similar, but probably not the same. The issue was reported to be solved in some openssl release but this still shows up in my error log.

The server has been setup from scratch. So there was not upgrade of Ubuntu or Apache ....
