Hi Geoff,

Yes. Looking at target/h/errno.h in my vxWorks distribution, I see that 0x37 (55) is ENOBUFS. I got similar messages on my vxWorks 5.4.2 target earlier this year. I tried increasing buffers... I tried John Sinclair's vxworks patch that he provided here...:

I swapped CPU boards... Nothing worked. Finally, I discovered that the network port for the CPU somehow got reconfigured to 100/full (long story). Going to 100/half solved the problem. Hopefully, your problem will be solved by just increasing buffers.
