not if the program is still running; it's not an error condition. the 
only case where fsck would help is if the whole machine crashed.

the traditional gotcha for "nonexistent file taking up space" is 
something generating a large log file, when someone tries to free the 
space by deleting the file. if the program writing it is still running, 
the file is gone but the space won't be freed until the program lets go 
of the file. lsof has a "deleted" indicator which can identify this.
