Error while seeing logs using loops

[Kudiyarasan]

Hi ,
 
    As  a new user of CVS , I have one peculiar
problem while seeing the logs using  loop.
Please see the following  piece of code ( shell script ) :
    case 1 :
         cvs    
log     ` find      source_dir/    
-type     f `
    This is working fine and we can get the proper result

But in
     case 2 :
        for     files     in     ` find     source_dir/     -type     f `
        do
            cvs     log     ${files}
        done

The result is not coming fully . i.e. the cvs server gets down at the middle and quits .
I can not analyze where the problem is . Can anyone help me ?! .

Thanks & Regards ,
