Not sure when this started, but I've got a couple of Linux servers where suddenly the Graphs tab on them blank. The page layout is all there, but the part under the heading Graphs where the graphs and netstats links and graphs should be is empty. Checked the apache logs and see nothing there indicating any problem and poller.php runs fine - one of them:
Observium Poller v0.12.4.3008
Starting polling run:

Ran poller also in debug mode and saw no errors - everything appeared normal. Just see this on a couple of CentOS 5.x and CentOS 6.x servers - have many others (same OSs) that are fine....
Ideas?
