wireshark causes NO receive errors with UDP

I have an issue on an Intel target board running vxworks. On occasion I see UDP packet receive errors. This is a low random event but causing us to miss valid messages. On our target we are unable to run TCP. When I run pcap on the Intel target board, I no longer see any errors and my packet receive errors go to ZERO. Therefore i am unable to reproduce my problem when running pcap.

Does pcap put the PHY into promiscuous mode?

What does pcap do that would make all UDP packets to make it through with NO errors?

thanks
