svc.configd: Fatal Error: Setting up main door failed

System took sudden shutdown, due to H/W issue.

Post H/W replacement, H/W become optimal.

So, while booting , system reported to run FSCK on root. And after executing FSCK, took a reboot.

Now, post that reboot system reporting the following error and going to maintenance mode.

"svc.configd: Fatal Error: Setting up main door failed"

Please help to understand is it related to any other H/W issue, or the OS might have got corrupted post the FSCK. As the error is being generated by the following "usr/src/cmd/svc/configd/configd.c" script.

Now, if the reported error is of OS only, then what does the term "Setting up main door failed", means.
