Hi,

hobbitd core dumps when receiving a status message on a host not in bb-hosts (snapshot 18 March 2008). This may, possibly, just be when the message comes from a Big Brother server, since that was the case here. I haven't tested when the message comes from another Hobbit server and I have now downgraded again. However, if needed, I could try reupdating. Backtraces follow...

Etc. More very similar to these. It would appear that every single one of these status messages causes a core dump as they happen at approx. 5 minute, or less, intervals.

Both of these hosts are commented out in bb-hosts, but hobbitd is receiving updates on them from a Big Brother server (where they should probably be commented out too, but I found I didn't need to with hobbit 4.2.0, so long as I don't mind getting the Ghost reports warning).

Kind regards,

Sebastian
