When you check the Processes tab in Task Manager do you see something unusual?
is there a specific process that use CPU?
Did you try reboot the server or the Esx?
Is there any errors in the event log?

the strange issuue that there is no log error any where.
the specific process are:
store,taskmge,w3wp,microsoft rplclient,my anti spam,msexchangerepl.
but it isnt balance.
i stopped to take a vm backup from that nachine couple months ago.
i ran consolidate comand at the vmware esxi to that machine i saw that
at that process the cpu was at 0% for 15 min.
i marked in red my anti spamexchange cpu

Are you still on Exchange 2010 SP1? If so you need to upgrade as that version is no longer supported. Exchange 2010 SP3 with the latest rollup is where I would start.

It doesn't matter if you have 100 systems on Exchange 2010 SP1.

Exchange 2010 SP1 went end of life over two years ago.
Exchange 2010 SP2 goes end of life in a few weeks time.

You need to upgrade your servers, because changes are made to the way that Exchange works, which could resolve your problems. If you refuse, then there isn't much more we can suggest because you are not on the latest version of the product which may well resolve the issues.

Is your VMWARE platform up to date as well? If not, then that should be updated as well.

There isn't much more that I can do to assist you then, as you aren't really accepting what I have said.

The fact that you have other machines that don't have the problem means nothing. It is completely irrelevant.
Your server is out of date - update and see if the problem continues, if it does then it is worth troubleshooting further.

I will repeat again EXCHANGE 2010 SP1 IS EOL. You should have updated years ago. Not patching is not really an option for anything that is exposed to the internet.

hi
i solved my problem like i thought:
i didnt update any sp+vmware updates.i move my server to another esxi server
then the problem passed away now my sever is on 0% cpu constantly.
its very important to check the hardware environment
we do now testing to our server to check where is the problem in the cluster.
