Hi All,

In our production server we are getting very high CPU utilization around 100 % . We are getting a lot of CPU alarms for it . We are having 3.75GB of RAM . Please find the added stack trace.

Hi All,

I would like to share some observations . This is a web client application . When there is only one client running . When I am doing any single operation . Example just hitting a button which is resulting in loading of records . The CPU utilization is 100 % . This is producing 100 % CPU spike . This is a very serious concern for us. This is servoy 6.1.3 running on postgres . The OS is windows .

Please provide some suggestions on this.

is that a stacktrace at the moment the cpu is at 100% ?  
is it really the java process that is then at 100%?

Because that stack dump everything is completely idle.

Hi Johan,

Thanks for your reply . Please find the attached stack trace during 100 % CPU utilization.

Hi All,

Can we have any Servoy admin settings which will result in improved CPU performance ?. Please provide any suggestions on this.

Thanks,  
Ashutos.

</div>

still nothing to see, your memory is almost not used, all threads are in a sleep/park/wait or blocking read/accept

Are you really sure that it is the java process that is causing 100% cpu? And then the java process of the servoy server?  
Because both stack dumps are doing nothing.

Hi Johan,

Please find the attached file for stack trace when the cpu is on 100 % utilization.

Thanks,  
Ashutos.

still nothing to see, you should really look what process is doing that 100% cpu, as far as i can see its not the java server process where you ask the stackdump on
