I have CCX 5.0.1 Premium and CUCM 6.1.3 Cluster. When I try to edit some agents from CRS Administration-Subsystems-RmCm-Resources - I see an error: "Error while handling the request". Agents are synchronized from LDAP. I didn't used BARS or upgrade CCX.
I try to clear flags, but it doesn't help.(http://www.cisco.com/en/US/products/sw/custcosw/ps1846/products_tech_note09186a0080ab4b8e.shtml)
