High CPU utilization

[raju_myadam]

Hello,

We have released an application into production recently. The application is built on top of community version of Alfresco 2.1. We are seeing high CPU utilization around 75% even when the system is idle with no user activity.
We are using following features of Alfresco -
Alfresco Document management
CIFS
FTP
Web services

Here are the environment details -
Hardware - Intel x86
Open Solaris 10
JDK 1.5
VMWare

Any advice on this behavior would be greatly appreciated.

Regards,
Raju

At night, there cpu action is normal. But in daytime i see spike's. We had a problem that the os harddisk was full of log file's. We resolved this, dont know if this could be linked to this problem.

Wich steps do we need to take next? Or even better what is this?

Also sometimes the system says Service temporary unavaible.

When rebooting i get an error that connection to java is refused.

After the reboot, al cpu spikes are gone, will keep an eye on this. But i still want to know what this is.

For search avaibility:
/opt/alfresco-4.2.c/java/bin -Djava.util.logging.config.file=/opt/alfresco-4.2.c/tomcat/conf/logging.properties -X

When i reboot the cpu is normal, after a night i get the cpu spikes back. Seems that a routine is causing this.

Found another thing, the spikes begin round 6:05, what is running on al fresco around this time?

At the reboot i get:
cat: opt/alfresco-4.2.c/tomcat/temp/catalina pid no such file

Found the problem, we changed a script and used to restart the java after the logs are cleaned, that caused the cpu peaks, i will post the original script with the conflicting rule this evening (For my own entertainment)
