[Bug 968021] [NEW] boinc stops on error after a few days (md5_file: Too many open files) in stderrdae.txt

[LeForgeron]

Public bug reported:

There seems to be a file descriptor leaks in the boinc process (client
side).

After a few days of fine loading the system, it would suddenly stop
working.

Relaunching it is usually ok (but actively managing a system running
boinc is rather not a decent solution).

Clue with the following command:

$ sudo lsof -p `pidof boinc`

The number of open file descriptor will keep increasing as boinc tasks
are completed. (more visible when the projects have fast tasks for the
hardware, such as sudoku or milkyway/nvidia)

A lot of entries are like:
