lsof was perfect, I couldn't remember that app-name, but it turned out I'd
already had a copy built. There were 3 candidates for having the most files open:
procname Number of open files
Are all of these excessive, or only one of them? Any notion, or any known
problem with any of these tree applications? I'm perfectly willing to go on
this by any vagrant memories you have hanging about.
