Hi,

We use OSF1 v5.1 here at Fermilab.  To solve this I added
-D_SOCKADDR_LEN to the command line.
Here are the notes from the send man page.

NOTES

  [Tru64 UNIX]   The send() function is identical to the sendto()
function
  with a zero-valued dest_len parameter, and to the write() function if
no
  flags are used.  For that reason, the send() function is disabled when
  4.4BSD behavior is enabled (that is, when the _SOCKADDR_LEN
compile-time
  option is defined).

I also had to modify base/src/include/os/alpha/osiSock.h to handle the
disabling of the send() function (see note above).  If this is not done
there are unresolved symbols at link time.  Here are the lines I added
to osiSock.h for the alpha.

#undef send
#define send(A,B,C,D)           sendto(A,B,C,D,NULL,NULL)
#undef recv
#define recv(A,B,C,D)           recvfrom(A,B,C,D,NULL,NULL)

On OSF1 we have seen an assert error from a client app with a connected
channel when we reboot the processor on which the PV lives.  Have you
seen this?
