fuser displays the PIDs of processes using the specified files or file
systems. In the default display mode, each file name is followed by a
letter denoting the type of access:
c current directory.
e executable being run.
f open file. f is omitted in default display mode.
r root directory.
m mmap'ed file or shared library.
To see what process it is:
ps -p pid...or in your case ps -p 3014.
Try man on fuser and ps. These are great commands that can help you a lot.
Sorry, I guess you responed whilst I was typing
You can also add -u to the fuser to add the user name of the person running the process. That might help.
