Hi Donepudi,

in the sapdb\data\wrk\IAC directory I found a file named KnlMsg whose content is updated anytime I try to start MaxDB. I hope it's the right file.

- login to the server

- traverse to \sapdb\data\wrk\IAC

- enter "protconv > knldiag"

This will create a text file with the content of the .xml log. Please share this log file.

Additionally look into this thread. Similar problem has been resolved.
