I'm seeing a blob of NULLs in the log file for a script that's using Log::Log4perl, like this: 

2315760   616f    2064    7661    7265    6761    7365    203a    2e30
         o   a   d  sp   a   v   e   r   a   g   e   s   :  sp   0   .
2316000   3133    3020    332e    2035    2e30    3233    000a    0000
         3   1  sp   0   .   3   5  sp   0   .   3   2  nl nul nul nul

The output is from the command od -ha cpt3.log.1 | less. Based only on the fact that the NULLs end on a block boundary, I'm wondering if this might be a problem with the hard drive. Thoughts?
