Hello. I took a look at the codes of TIdUDPListenerThread.Run method. I found the FReadList.SelectRead(AcceptWait) seems not necessary. What is the real use of it, please? Thank you. //////////////////// IdUdpServer.pas //////////////////// .... .... procedure TIdUDPListenerThread.Run; var PeerIP: string; i, PeerPort, ByteCount: Integer; begin FReadList.SelectRead(AcceptWait); // After I delete this line, IdUdpServer also works well. for i := 0 to FReadList.Count - 1 do try ... ... ... end; ....

SelectRead() waits for the socket a become signaled indicating that data has arrived on it, before then reading it. I assume that you are using Indy 10, is that correct? There is no FReadList member in TIdUDPListenerThread anymore. In older versions of Indy, TIdUDPServer ran a single TIdUDPListenerThread that continuously looped through all of the available Bindings one at a time. That meant that the server could only process 1 packet socket a time, regardless of how many clients were sending data. TIdUDPServer has since been re-written awhile ago to run multiple TIdUDPListener instances now, one for each Binding, much like TIdTCPServer does. This way, multiple clients can be processed simultaneously. You should consider upgrading.

Do you mean there is a newer version now ? Indy 11 ? No, not 11. But Indy is in constant development. The daily snapshots of version 10.1.5 have newer code than what you showed earlier.

There have been a lot of 10.1.5 releases. The version number has not been rolled forward for awhile. Again, the code you showed earlier is NOT what is in the current snapshot.
