Martin,




Have you disabled Large Receive Offset (LRO) on all the Elastic Sky hosts?

So 5.5 is supported with CUCM 9.1.x

 
So the question is: Why do I have CUCM at 100% CPU? Only hard reset helps at 
this point.
 
Thanks, Martin

Guys,
 
since 3 weeks we are running our UC Environment (CUCM, Unity Cxn, IM&P) on ESXi 
5.5. At Friday we setup new vCenter 5.5 and added the esx hosts.
 
Since saturday, all machines are stuck in 100% CPU after a few hours. Sometimes 
all machines at the *same* time! They don’t reply Ping (ICMP Echo), and
 CPU is at 100%.
 
CUCM and Cxn are on 9.1(2)SU2a (9.1.2.12901-3).
 
Someone has any idea? Is 9.1.x not supported on vSphere 5.5?
 
Thanks, Martin
