SAI_PORT attribute get failures

[mcallisterjp]

Running on the OPX v2.2 VM, I'm getting thousands of these logs in syslog:

Feb  8 18:08:29 opx_vm opx_nas_daemon[595]: [ev_log_t_SAI_PORT:Switch Id: 0], Attr get for port id 0x1000000000011's attr index 0 attr id 8 failed with err -65536
Feb  8 18:08:29 opx_vm opx_nas_daemon[595]: [ev_log_t_SAI_PORT:Switch Id: 0], Attr get for port id 0x1000000000011's attr index 0 attr id 8 failed with err -65536

Feb  8 18:08:29 opx_vm opx_nas_daemon[595]: [ev_log_t_SAI_PORT:Switch Id: 0], Attr get for port id 0x1000000000032's attr index 0 attr id 8 failed with err -65536
Feb  8 18:08:29 opx_vm opx_nas_daemon[595]: [ev_log_t_SAI_PORT:Switch Id: 0], Attr get for port id 0x1000000000032's attr index 0 attr id 8 failed with err -65536

They're not correlated with any other problems or failures that I've noticed, and seem to come in bursts 20s apart.

What other diags can I get you to help with this?
