Random inband traffic drops after enabling ERSPAN-source session on Nexus 5500 switch. 
Affected inband traffic is traffic destined to the switch SVI address of the VLAN used to send the ERSPAN traffic and which ingresses via the VPC peer-link.

This was observed on Nexus 5500 switch after an upgrade from 5.0(3)N1(1c) to 5.2(1)N1(3). Switches that had other upgrade paths may be affected as well.
