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.

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.
