i have never heard of a heat sink degrading but apparently it does happen (see
article on heat sink degradation) ... if the issue only started recently without any changes to the environment -- which judging from the servers you mentioned (v440 and v280 both of which are already out of life) that may have already been there for years -- it is very possible that heat sink degradation could be the cause of the overheating ...
hopefully your customer has sun/oracle support or has access to a cpu parts supplier ...

I applied 109147-39 to, oh 15 or so various systems all running Jumpstarted Solaris 8. When I hit the first two V440s, they both failed with Return code 139. All non shell commands segfaulted from then on.

SC Alert: Correct SCC not replaced - shutting managed system down!
This is cured by moving out battery from ALOM card.
Now server start to loop during the testing.

Hi,
I was asked to connect a KVM screen to a Sun Fire V440 last night so I connected it up but no joy and nothing on the KVM screen. I was told that a reboot may fix the problem so connected to the ALOM and rebooted. On the plus side, the KVM screen now works but I lost the ALOM connection.

LEARN ABOUT PHP
com_event_sink
COM_EVENT_SINK(3) 1 COM_EVENT_SINK(3)
com_event_sink - Connect events from a COM object to a PHP object
SYNOPSIS
bool com_event_sink (variant $comobject, object $sinkobject, [mixed $sinkinterface])
DESCRIPTION
Instructs COM to sink events generated by $comobject into the PHP object $sinkobject.
Be careful how you use this feature; if you are doing something similar to the example below, then it doesn't really make sense to run it
in a web server context.
PARAMETERS
o $comobject
-
o $sinkobject
-$sinkobject should be an instance of a class with methods named after those of the desired dispinterface; you may use
com_print_typeinfo(3) to help generate a template class for this purpose.
o $sinkinterface
- PHP will attempt to use the default dispinterface type specified by the typelibrary associated with $comobject, but you may
override this choice by setting $sinkinterface to the name of the dispinterface that you want to use.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
COM event sink example
<?php
class IEEventSinker {
var $terminated = false;
function ProgressChange($progress, $progressmax) {
echo "Download progress: $progress / $progressmax
";
}
function DocumentComplete(&$dom, $url) {
echo "Document $url complete
";
}
function OnQuit() {
echo "Quit!
";
$this->terminated = true;
}
}
$ie = new COM("InternetExplorer.Application");
// note that you don't need the & for PHP 5!
$sink = new IEEventSinker();
com_event_sink($ie, $sink, "DWebBrowserEvents2");
$ie->Visible = true;
$ie->Navigate("http://www.example.org");
while(!$sink->terminated) {
com_message_pump(4000);
}
$ie = null;
?>
