Hi,
Over the weekend we received these error messages from an mv5500 running vxworks 5.5 and epics 3.14.6. As far as I can tell this is an ENOBUFS error. Is this the correct interpretation?
CAS: UDP send to "131.225.231.247:35139" failed because "errno = 0x37"

What buffer needs to overflow to get this error? I thought the only UDP messages from an IOC were beacons to port 5065. What are the other UDP messages to ports other than 5065? Could this indicate a problem somewhere else on our network?
Thanks, Geoff
