Xymon crashes 🔗 link

Hi all,

I've got the following problem:

I used to run Xymon 4.2.3 on FreeBSD (using the ports collection) and it 
worked fine.
However, when I upgraded to 4.3.2, I got all sorts of weird behaviour, so 
I decided to start from scratch.

So I uninstalled Xymon, deleted everyting related to it and then installed 

a fresh copy of Xymon 4.3.2 (also via the port-collection)
The installation goes fine, but when I start it up, the html files aren't 
generated.
It seems that xymond crashes for reasons I don't understand

I did some digging and I see the following:

Line 6 surprises me, because 'Amp2hi-test' is one of the hosts that I used 

to monitor, but I removed all the old configs etc from the server.
I've started up xymon several times and sometimes I see other 'old' 
hostnames in the output file of xymond.core
It appears that I didn't completely remove all traces of the old 
installation after all...

Any help would be appreciated,

Dennis

Looks like something weird in your configuration - that "directory" name 
doesn't look right. Check your configuration files - especially the 
xymonserver.cfg and tasks.cfg files, this is something that happens very 
early in the setup.

Maybe tasks.cfg has a "directory" include pointing to a non-existing 
directory. Maybe xymonserver.cfg is missing or unreadable.

Maybe your config files are not ascii, but in UTF-16 format.

Are you logging all tasks to the same logfile ? It looks like it, and 
this makes it difficult to separate out which task logs an error.

xymond shouldn't be reading xymonclient.cfg - it should use 
xymonserver.cfg ...

Yep, something's lying around somewhere.

Henrik

No. I have seen this before, and I forgot to note it.

In my case there was a permissions problem on either the directory, or a file 
in the directory. The function handling this does not catch errors in opening 
the file.
