Hi,

To ensure that we have proper version/platform/compiler information,
please make sure you fill out the appropriate problem report form
(PRF), which is in

$ACE_ROOT/PROBLEM-REPORT-FORM
$TAO_ROOT/PROBLEM-REPORT-FORM

or in

$ACE_ROOT/BUG-REPORT-FORM
$TAO_ROOT/BUG-REPORT-FORM

in older versions of ACE+TAO. Make sure to include this information
when asking any questions about ACE+TAO since otherwise we have to
"guess" what version/platform/compiler/options you've using, which is
error-prone and slows down our responsiveness.

That's no surprise - you're probably sending the packets faster than
the kernel can allocate buffer space for them.

>> Do I need to set any flag in send and recv methods of ACE_SOCK_Dgram ?

No, that won't make any differencde - plus, there are no such flags.

That assumption is misplaced - you can't assume ANYTHING about the
reliability of UDP. If you want to make sure all the packets are
received, you'll either need to use TCP, UNIX domain sockets, or
implement a retransmission layer atop UDP.

Take care,
