What happened after resolving of the IP has failed?

[Joerg Maschtaler]

Hi,

on my Tor server (0.1.1.19-rc) i've got the message in notices.log:
---snip---
[warn] check_descriptor_ipaddress_changed(): options->Address didn't
resolve into an IP.
---snap---
After this message no further message was written (for ~2 hours).

My question is:
Is this Tor server "offline" and has to be restarted or would it try to
resolve its name further on and only doesn't send a message if it succeeded?

thx,
joerg
