[Mailman-Users] Cookie problems?

[m.lavy]

Hello, I run three separate Mailman servers (all low volume). Yesterday 
evening I encountered a weird problem with 2 of them:

It seemed as if (a) cookies had stopped working or (b) a strange permissions 
problem occurred because although I could log in to the admindb page for all 
my lists with no problem, an attempt to approve a vetoed message just 
returned me to the login screen. Likewise, an attempt to switch between the 
various admin pages led me straight back to the login, even though I could 
happily authenticate to each individually. 

The strange thing is that this happened only on 2 out of 3 machines, even 
though Mailman is configured identically on all. I do not think it is a 
webserver problem because the two machines run different software. Even more 
strangely, today everything is working fine! 

I'd be grateful for any thoughts.
