[Sugar-devel] Sugar web activity wait 1 minute at startup

[Lionel Laské]

Hi James,

Thanks for advice.
I've tried tcpdump. See an extract below or full trace here [1].

To be honest, I'm not familiar with tcpdump log. BTW I don't see any error
but I see the same 1mn delay in the log (between 21:30:46 and 21:32:27). So
I guess it don't come from a DNS timeout...

           Lionel.
