.pid files are usually Process ID files often used as part of a half- 
arsed locking mechanism, or so a "stop" function can determine the  
"active" process. Check permissions to the file and the directories in  
the path. Probably can just delete the file and let it be recreated on  
start.

A Google search on mysql and pid may help you too.
