Yeah, I've worked a lot with TCP and it was really no problem requesting a
next packet after each, it was very fast.
UDP offers some other valuable features though.
How do you manage missed/double/wrong ordered packets? I thought of making a
buffer to store a certain amount of packets.. say... m

Each packet got some sequence ID and "alive packets" were sent from time
to time. Also there was no special acknowledge packet - each received
packet contained the last successful received ID of the sender. If one

Hello Edward,
Possible you ran out of buffer space. Winsock use non pageble ram. The
non pageable ram can grow to max 1/8 the size of total ram. Depending on
traffic each socket need about 6 KB of it. And lots of other
applications uses that part of RAM also (all overlapped IO for example).

Simply enable NTML authentication at the HttpCli component (update to the
latest ICS if your version doesn't support NTML). And provide the require
credentials. Select your IS
Hi Wilfred,
Please can you explain this a bit more.
I also have this problem, and have actually had to resort to changing my
system design just to get it working acceptably.
What influences how much buffer RAM is used by each socket. Is it data
through the socket? Also, what is the relevance o
Hi Wilfried, thank you for replying.
How do i check how much non pageable ram is available?
The test i did for Windows Server 2003 runs on a
system with Xeon processor and 3gb ram. It

is very strange compared to the other test that

Have you tried with one of the server demos included with ICS ?
Just to see if it is related to your code or elsewhere.
It is also possible that windows run out of other kind of resource. Have you
"instrumented" your program with - for example - FastMM which could tell you
about memory leaks ?
