[Xorp-users] Defining a new module, xorp 0.3

[Pavlin Radoslavov]

Thomas,

First, I'd like to apologize for not answering your
email much earlier. We got hit with the email virus/spam and while
dealing with it we neglected responding to legitimate email :(

I think we were able to reproduce the problem you had.
It appears that the problem is in the parsing of the configuration
or template files, but we are yet to confirm that and to apply the
appropriate solution. We will try to fix this as soon as we can.
In the mean time, could you send us the complete log message when
you start the rtrmgr.

Thanks,
Pavlin
