High cpu utilization after upgrade to 12.10

After upgrade from pms 12.0 to 12.10 java process on server ( fspms) uses permanenty above 16% of CPU. Before upgrade it was much less. PMS manages only 70 stations, such a utilization is all the time, no changes. SLES linux 11 SP4 on virtual machine, 1 CPU, 3GB ram. How find out what is happening?

Hello,

 

> 1 CPU

 

2 cores are recommended.

 

> 3GB ram

 

This should be a 32-bit operating system. The 64-bit system doesn't make sense with less than 4GB of RAM, because 64 bit program codes take up a lot of space.

There is a built-in diagnostic and support data collection tool, called FSDIAG in F-Secure products or you can download it separately  from here:

I have the very same problem. My machine is an OpenVZ containter with debian 7 32bit. I tried a fresh install on a different container and it shows the same issue.

 

Here you can download my fsdiag.tar.gz

Hello, 

 

we're currently investigating the problem that in certain environments PMS process can show some unexpected CPU usage. The workaround for now, if the system becomes too loaded, is to add more CPU units  to the virtual machine.

Thank you for answer,

I assign second CPU and extend ram to 4Gb. Generally it didn't change situation. Still java process uses hi amount of CPu. Fortunately my system is not overloaded.

Dear Dandelion,

 

Have found out the problem's cause during the investigation? Will there be a hotfix for the unusually heavy resource usage problem?

 

Thanks in advance, Yours Sincerely:

Re: High cpu utilization after upgrade to 12.10

As of now, we are in the process of tracking down the root cause. 

 

The load tests reveal that, although PMS process may under certain conditions show abnormal CPU activity, it does it "softly" in a way that it doesn't affect the overall system performance. 

 

However, we realize that this behavior is not appropriate and wer're currently working on solving this problem.
