Whether it does or not, you should not run with "-D" in production. Interactive debugging of Postfix daemons should only be enabled briefly to aid in identifying software problems with Postfix or the libraries it uses. So yes, remove "-D" all from master.cf entries, and run "postfix reload" or perhaps better "postfix restart". If the reason for the panic is some sort of debugger side-effect (highly likely, though not yet 100% clear what the exact mechanism is), then not debugging should help. -- Viktor.
