I've got Trac installed, but often get this error when opening a trac
page:
Oops...
Trac detected an internal error:
no connection to the server

OperationalError: no connection to the server
It seems like it cannot connect to postgresql? Waiting a little bit,
and tretrying, makes it work again. Does postgresql somewhere has a
limit on the concurrent number of connections per user? I've got
max_connections = 500
but there do not seem to be that much connections (it's a trac install
with not even 10 projects and the problem is triggerend when one users
quickly tries to visit the different projects one after another).
What could this be?
