The failures are probably partly triggered by the machine running out of memory.
It runs services on mod_python, which apparently slowly leaks. Someone (who?)
with root access on the machine needs to restart Apache. (Note: "apachectl
graceful" is not enough to correct this, it needs a real restart of the process.)

Longer term solution is to move out of mod_python (mod_wsgi likely, going to CGI
will create other performance problems), or to transition the stuff there to a
more beefy server.
