socket.getfqdn deadlock

[vvikram]

Hi,

I am getting deadlocks (backtrace pasted below) after a while at,
presumably, a socket.getfqdn() call in a child process .

Fwiw: This child process is created as the result of a pyro call to a
Pyro object.

Any ideas why this is happening?

Thanks. Regards,
Vikram

Are you sure it is not timing out, waiting for a DNS reply?
