You don't say in what way this dies.  There are any number of ways things 
could be misconfigured.  Please provide more details.

Are the thread creates failing?

Is the network stack running out of memory?

Does the ttcp network demo test run ok?

If you are getting a fatal error, then it should be being reported.
I don't recall what the pc386 BSP does for a fatal error handler but
the error code should be indicative if that is the case.

There are lots of minor things that could be wrong.  I have seen numerous
packages that don't check error codes well enough.  They could be
having a priority ceiling violation on a posix mutex and not really
locking things.  Does the code assume creates work and they are failing?

How may threads, mutexes, etc do you have configured.
