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.

Hello,
tonight my dovecot upgraded to 2.3.17 and completely broke on recent CentOS 8 installation.
I found the service in status

This seems to be like a bug as no configuration was changed by me in the middle of the night.
I recall there were similar errors/bug reports in the past were it seemed it was managesieve but wasn't, people had some misconfigurations in the dovecot.conf. I did not change my dovecot.conf since April.
But maybe here it is a pigeonhole issue.
As I did not find any reason for it I changed the repo and downgraded to 2.3.16-2 now and it runs without any flaws, like all the time before. I had no time to investigate this any longer thand 2 hours with 2.3.17 installed as this is a production server and I need the email access. I also did not find anything adressable in the logs.
