PROBLEM:  (QAR 63229,61253)    (Patch ID: OSF435-026)
********
This patch fixes a problem with NFS conversion of a file's vnode number to
a file handle number.  When a SUN client accessed files on a DIGITAL UNIX
server, the file id was truncated improperly during the conversion,
generating EOVERFLOW errors.  As a result, an NFS client was receiving
EOVERFLOW errors.

This patch fixes a situation in which an NFS server system experiences system 
hang and a "malloc_mem_alloc: no space in map" message is written to the 
console.

Avoid system hang caused by memory leak in 12k malloc'd buffers.  The problem 
is that when the NFS server receives a duplicate request for an operation that 
is in progress, a memory leak causes the system to hang.  Also wasn't returning replies for gathered writes to the socket on which they
arrived from.
