Problem: after copying server 'mysql01' to 'mysql02' and forgetting to adjust DNS-name for interface 'eth0' I get an error in the WebGUI and an exception in /var/log/cobbler/cobblerd.log. All makes sense to me.
I click System List, and I get the following apache response:
Forbidden You don't have permission to access /cobbler/web/ on this server.
and the following message in /var/log/cobbler/cobblerd.log:

What can be wrong?
Do you need more info?

Your problem appears to lie within the code to delete new objects from cobblerd's internal cache.

Cobblerd has some logic to allow a new object handle to be created, modified, and then saved. This seems to be a bug in this logic (we were fixing other caching bugs Friday, and may have traded one for another)
Anyway, if you restart cobblerd, the WebUI will work again...
Might require a 1.6.2, I'll pound on it fully Monday to see if I can replicate this. I'd be curious to know if you save a system successfully and wait 15 minutes, if you get the same problem, or if it only happens with aborted saves.
Command line additions should not be affected.

This is actually a seperate error.

Just to clarify, this last thing is "normal". We're just logging it for sake of completeness.
The first message is not normal.

I will test this, and let you know

I understand, I posted it to give the other error message some context. Shouldn't this exception message be sent back to the WebUI?

Yes, most definitely.
Possible chance the first was masking the second.
I'll look at this after I get the first item settled.

I just tested this and the error seems to report fine now (after the cobblerd caching fix)
