What is the switch model?  Is this a chassis or is this a stack of switches?  Describe it all.  

 

From the looks of the "sh logs", I am suspecting line card 3 or switch stack member 3 is about to fail.

 

One way of testing is move some (not all) of the affected ports to different line card slots or switch stack member and observe for 12- or 24 hours.

hi mate.

cisco WS-C3750V2-48PS
and yes it is a stack of switches.

Switch Ports Model                       
------ ----- -----                      
     1 52    WS-C3750V2-48PS        
*    2 52    WS-C3750V2-48PS          
     3 52    WS-C3750V2-48PS            
     4 52    WS-C3750V2-48PS   

and yeah. initially dats what i did. 
transferred some affected ports and now im observing.

"From the looks of the "sh logs", I am suspecting line card 3 or switch stack member 3 is about to fail."
=> majority of the affected ports where from Stack 3 though theres a few from stack1 and 2.

see below:

Ma-ayong buntag.

 

Ok, post the following commands: 

 

1.  sh  Interface FastEthernet3/0/41; 

2.  sh controller e  FastEthernet3/0/41;

3.  sh version

 

What are these clients connected to the ports?  Are these ordinary PCs?
