Hello!

From the description you gave it is hard to find out what is happening without some more information.
Can you share your configuration, please?
Do you use the internal source, wildcard file-source?

We also have a tool that can be used to collect environment and information called 'syslog-ng-debun'.
It can collect sensitive data, so be sure to replace/remove those before sending the debun, e.g. IP addresses and passwords from config, etc.
https://github.com/balabit/syslog-ng/blob/master/contrib/syslog-ng-debun
https://github.com/balabit/syslog-ng/blob/master/contrib/README.syslog-ng-debun

As you are using Solaris as syslog-ng 3.12.1 have you built it from source or used a package?

Best Regards,
Gabor

The data in the core dump would need to stay in my hands, so that's no good.

I'm going to have to toss syslog-ng out :(
Silencing sources without logging anything, when things went wrong in the most common way, is a complete deal breaker.
