Hi everybody

For a while, I have EPICS 7.0.6.1 running on some vxWorks 6.7 IOCs. Now I upgraded one of them to vxWorks 6.9 and get those strange errors:

Error on UDP RX 172.20.4.25:48599 -> 172.20.255.255:5076 at 47 : no more data in UDP packet : 71:71 for 1

The sender IPs belong other EPICS 7 IOCs.

I found the messages to pvAccess/src/remote/blockingUDPTransport.c, but it is hard to understand what it means or why it appears on vxWorks 6.9 but not vxWorks 6.7.
It may be that I configured something wrong on vxWorks 6.9 as I had to migrate the BSP for the no longer supported architecture from 6.7 to 6.9 and had difficulties to get networking running initially.
But networking works now and neither CA nor PVA nor NFS show any problems.

Any ideas? [Looking in Michael's direction]
