Do you have apache trending graphs enabled? If so, did you enable the status page in your apache configs?

Hi all
My Xymon server 4.3.10 is burning the CPU cycles when we view multiple graphs, like the trends page, and takes about 5 seconds to render a single graph in a single-graph page view.
It's a Sun Fire X4150 with 4Gb of RAM, running Solaris 10 update 5..
Version Location Tag
Intel(R) Xeon(R) CPU X5460 @ 3.16GHz CPU 1
Not a very powerful box, and a bit dated, but I have seen significantly better performance on far lesser systems. So I am not really thinking the issue is with the hardware. It's been slow since it was installed. If I view the trends column, I can see the CPU load jump from below 1 to over 10 at times. Running prstat or top in another window while viewing the trends column, the process ranking by CPU gets dominated by showgraph.cgi, owned by the web server user. Top under normal conditions. CPU states: 99.9% idle, 0.0% user, 0.1% kernel, 0.0% iowait, 0.0% swap Top rendering the trends column. CPU states: 0.0% idle, 93.8% user, 6.2% kernel, 0.0% iowait, 0.0% swap
Also getting this error (128)Network is unreachable: connect to listener on [::]:443 in my Apache error.log file, repeated every second while rendering the graphs. And from time to time, I get this one. File does not exist: /opt/csw/apache2/share/htdocs/server-status
Anybody seen anything like this? Perhaps know of somewhere I can look for more info?
I have looked at this http://lists.xymon.com/archive/2014-January/038780.html But it doesn't seem relevant. Only 2 errant files, and deleting them made absolutely no difference.
