Stress and crash

[francoisTemasys]

After stressing the Bridge with 9 users (on 3 computers) in the same conference room, the server crashes with the following error:
(process:9240): GLib-ERROR **: Creating pipes for GWakeup: Too many open files

I don't remember that janus is opening files.

I also see this error message popping intensively:

Hi Francois,

you need to increase the number of file descriptors that can be opened on the machine. By default this is a quite low number (1024). This can be increased using ulimit.

Where does this file descriptor requirement comes from?
Wouldn't it be interesting to add this requirement into the install script?

And thanks for the quick solving answer

Actually that's not a requirement, but AFAIK a good practice most deployments that make use of a lot of file descriptors typically make use of. You can find a good description on the problem and possible solutions here: http://docs.mongodb.org/manual/reference/ulimit/

You're right in saying it should be clarified, though, as I realize it may not be obvious. I was preparing some kind of FAQ to add to the documentation, basing on questions and comments here and on the google group, so I'll add this to the list.
