Do you have the Server Monitor turned on (assuming you are running ColdFusion Enterprise)? If so, try turning it off. Some of the monitoring tasks can put excessive load on the server and result in crashes.
Do you mean \ColdFusion10\cfusion\lib\neo-metric.xml ? It's syntax has cfmetics and cfstat.
Suggest take a copy of xml by way of backup then edit.
Not a fan of either metrics or cfstat on CF10 to monitor performance myself. All the best with that.
thanks Carl, all those selections are off. still experiencing the same error.
Wonder will passwordreset (CF10\cfusion\bin) help to get your CFadmin login ok?
Sounds like there is a lot more not working than just the metrics problem with the 2 or 3 hour up-time. Perhaps it would be good to know if you have made adjustments to CF by way of CF updaters and corresponding tomcat connector increments as well as Java and tomcat tune settings to cope for the type of workload been put thru?
HTH again, Carl M.
