2.3.17 broken on CentOS8 / bug

Robert Nowotny
2021-10-30T10:59:56Z

the reason is :

ssl_ca = </etc/ssl/certs/ca-bundle.crt

if "ca-bundle.crt" is too big, You will get that error.
this should be fixed, but as a workaround You might pull out the
certificates You need.
I personally wait for the patch and stay at 2.3.16 for the time beeing.

yours sincerely
Robert
