I have one our of 8 hub/mailbox servers having high CPU split between the Store.exe and msexchangerepl.exe processes.
2 AD sites 2 CAS servers in each site 4 hub/mailbox servers in each site the DAG spans the site with each mailbox database having 2 copies in each site. (FSW is in a third site)
All servers are 2008r2 with the latest patches.
These are all virtual machines on vmware.
The server having the high CPU has no active databases on it just copies (4 of them).
Not showing any consistent errors or warnings. it has been doing this for over a week now. It will spike to 100% for a while then operate between 80 and 50% for a while then in the evenings drop to almost normal (5%- 15%) like the other hub/mailbox servers.
Restarting services or rebooting has little to no effect.
This server also houses the public folders for this site. I have dismounted them and it makes no difference. I also dismounted the non DAG replicated database (which has no mailboxes on it) - no change.
and I'm sure I'm forgetting something else I tried....
Thank you in advance for your help!
