This happened to us awhile back when we were opening a file using ftp
rather than nfs. The file wasn't getting closed between writes to the file
and so the file descriptor wasn't getting released. I think it happened
after we installed a tcp wrapper for in.ftpd on the host where the file
resided. Opening the file w/ NFS solved the problem.

we have had the same problem before years.
We decide to increase NUM_FILES to 255.
Additionally I've modified the Mbufs-Configuration to increase the network
performance. ( defaults in ../target/h/net/mbuf.h )
