Hi
We have two more or less identical machines with very similar software
installs - both Mandrake 7.0, both have had exactly the same security
fixes (mostly to BIND), both run Apache 1.3.9 with mod_jserv as user
webserver, group webserver (201, 201 in both cases).
Recently we've installed mailman on both machines, using (as far as we
can see) identical installs. One works well, the other doesn't work.
What goes wrong? Well, for most actions performed through the Web
interface, the user experiences timeout on the browser, and we get the
following written to the console:
Security: denied hard link to 509.511 for UID 201, EUID 201, process
python:8347
We get the following written to /opt/mailman/logs/error

Sure enough, in the /opt/mailman/locks directory we find dead
lockfiles. The *very* odd thing is that these dead lock files have
dates one day in the future with respect to the system clock:
[simon@beesianum simon]$ ls -l /opt/mailman/locks/
total 20

We've done a Google search on 'mailman denied hard link' and have
identified that this problem has occurred for other people:

While all these messages report the problem, none that we've found is
followed up with a suggested solution...
Any suggestions very much welcomed!
Cheers
