I suggest you to take a look at the meaning of the data showed by "/proc/loadavg".
See: http://www.luci.org/luci-discuss/200210/msg00055.html for more details. In my opinion your loadavg of 3.0 means only that in your application there is an average of 3 task waiting for running on the CPU. This in general doesn't mean that the CPU load must be 100 %. Maybe there should be some scheduler issues. If you take a look into your app sources maybe you can know more about what happens. -----Messaggio originale----- Da: diba...@libero.it [mailto:diba...@libero.it] Inviato: martedì 22 settembre 2009 10.15 A: Bosi Daniele; linuxppc-dev@lists.ozlabs.org Oggetto: R: High load average but low cpu (xenomai can be the explanation?) It is an AgentX subagent, it does a lot of things like accessing the hardware, handling messages from the main snmp agent received from an unix socket, writing files on jffs2 partition, polling hardware for alarms. If I kill it, the load goes down. Anyway the subagent only takes 2-3% of the CPU..
