i am getting exception.database already in use(which comes when lck file gets generated.)
Here only in one linux server its giving me this exception.
in all others lck file gets generated only when i acceseed the url of site at least once. second time without deleting i get this exception in all normal case.
But only in one linux machine i am unable to figure out why its reacting like this.
is there any dependency on this what i can find out and solve.

or please guide me what to do here.

i am fully confused.
thanks.
