Every binary throws out that error, every LMTP delivery... basically every time any dovecot binary is executed. I am unsure if this is configuration related or not, but intuition says it is an issue with a kernel feature or compiler issue.

Since I don't know what specifically this would relate to (and I don't quite remember the command to send the "safe" version of the configuration), I am sending this message in hopes that whatever is needed can be asked and I will provide it.
