[Xymon] Formatting errors on log files

[Greg Krpan]

So the memory usage on the machine is fairly high.  This system is a VM,
and was built with only 2GB of memory, of which about 1.8GB is in use.  I
have a maintenance window coming up this week where I am going to increase
the available memory to the server, but I will also try to inject the 2
MALLOC debugging that you suggested into things as well to watch for
additional issues as time goes on.  Hopefully that can help to identify
where the problem lies and I can be a testbed to help determine a
resolution.

Greg.
