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.
