I've seen similar problems as well.  I can't say what the actual cause 
is, but the following changes more or less resolved this problem for 
me:

- increased number of open files (somewhere in the POSIX fileio package 
I believe)
- increased number of open sockets
- increased size of mbuf arena by a few hundred K
- upgraded to latest eCos code from CVS (from 2.0 in my case)

Sorry I can't offer a more precise solution, but maybe this will help.
