One more thing OS is Windows 7

There is such line in your log “The database is already in use by another process”. Make sure you don’t have multiple Openfire instances running. Maybe you have it installed as a service and also try to launch it via Launcher.

Finally able to restart it.three errors were there.First multiple instances as told by Wroot.Second,while registering for openfire admin account first time changed domain to system ip.third,Not running it as system admin as I’d installed it in Prgram Files,therefore,it was unable to access some files on re-run.
