Sorry Again
I tried
$ tail logfile > logfile

result : no change in file size ,for a fraction of a second,file size droped to zero but again regained its original size.

I have a wierd suggestions:
I know the 'fuser' of that particluar file, is there any way by which that I transfer 'fuser' to temp-file and clear the logfile and bring the fuser back to actual logfile.

NB : Even if I rename the file,the renamed file keeps on updating.So process Id has some role in this process.

Please advice.
