Hello Éric, > Actually I thing that this exception was raised because of the > architecture of my software and I need an opinion about that.
What is exacly the exception message ? > when I have some hosts down. My app has a Timeout parameter (Default 4 > seconds) when if it doesn´t receives video from the host it closes the > connection and opens it again You have to call Close (or CloseDelayed), and in OnSessionClosed you post a message to custom message handler where you connect again. > I have tried to do this reconnect to the host by 2 ways, by Closing > and Opening the TWSocket connection again and by Destroying and > Creating a new TWSocket component each time it needs to reconnect to > the host (at each 4 seconds) Both are good. Closing / opening will be the most preferabel in my opinion. > on the first way (Closing and Opening) I > got some EOutOfMemory error on ICS Is it 'no buffer space available' ? Because Windows keep the socket for a while after closing the connection (I think 2 minute). Sockets are made into the non paged memory pool which stop growing at 1/8 the size of physical RAM. So with the amount of sockets in TIME_WAIT state + the sockets you create it could be that you run out of memory ? Consider that a socket takes around 2 KB, and that overlapped IO (used by winsock) eat also in blocks of 4 KB. > and on this second way (Destroying > and Creating the TWSocket component) I got that exception message at > the beggining of the email. I cannot see the exact exception message. Can you give it ? > Can you tell me if this reconnection procedure that I made (each 4 > seconds for down hosts) is dangerous to TCP at any way? Definitively not. But possible you have a memory problem because of the TIME_WAIT sockets (nothing to do with ICS, but that's how winsock works). > Another thing that I have thinked is that if I need to wait the > TWSocket connection error message before trying to reconnect to the > host or I can close if before receiving the error message? Use OnSessionClosed. But do not reconnect from within the event handler, but post a custom message so that the reconnect is outside the event. --- Rgds, Wilfried [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html http://www.mestdagh.biz -- To unsubscribe or change your settings for TWSocket mailing list please goto http://www.elists.org/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
