Ah,
        I wasn't thinking about apache logs, I was looking in xymon logs. Yes, errors:

[Thu Sep 05 15:12:22 2019] [error] [client 10.139.63.193] 2019-09-05 15:12:22.832251 Sendto failed: Connection refused, referer: https://nsmdenvp117.corp.intranet/xymon-cgi/svcstatus.sh?HOST=nsmdenvp185&SERVICE=ConfigPulls

        And yes, the rrd file exists in the right directory. It only has 1 data point at this time, but again. Running rrdtool graph on that file produces a graph

        Oh, I never mentioned before.   This is CentOS 6 with my own build for 4.3.21.  I'm starting to move to the Terabithia repo, but haven't got there yet on the server.

Paul.

A 500 ISE isn't a good sign. Is there anything in the web error logs?

And just to confirm, the file does actually existing in the RRD
directory as expected?
