Socket Error 10053
for malware, as some malware is badly written and will use a lot of connections Use a program such as TCPView or NETSTAT (with the -b parameter) to see which programs have connections open Current versions of Windows can support many thousands of IP connections at once. Server versions can support more than desktop versions if you have a busy server, so it is unlikely that VPOP3 on its own will deplete the socket buffers, and the problem is usually some other software. how_to/10055.txt ยท Last modified: 2015/09/23 13:46 (external edit) Page Tools Show pagesourceOld revisionsBacklinksBack to top

It works perfectly but socket error after some time, the internet connection begin to fail and finally I get this error (10055), which means that my app run out of buffer space. Actually I think I am only using 2 sockets with the code i did by myself, but it's true that I'm using a 3rd party library that I have no idea how it's implemented. I've read that there are lot of literature about this trouble, so I am not socket error 10054 the only that suffers from it, but I cannot realise how to solve it, or at least, by-pass it, because when it fails, it makes my computer to lose internet connection. I've tried it by catching this error and when it occurs, doing a WSACleanup(), WSAStartup() even when it's not the best practise... but my app still get stacked in this error. Any advice will be pretty much appreciated. c++ c windows sockets winsock share|improve this question asked May 23 '13 at 11:08 aluncob 30110 1 Post some relevant code. –Rohan May 23 '13 at 11:10 Can you post some of your relevant source code? Maybe there is a memory leak or something. –Roger Rowland May 23 '13 at 11:10 add a comment| 2 Answers 2 active oldest votes up vote 2 down vote accepted Usually this happens when you dnt close your socket properly. Make sure you have both shutdown and closesocket when you want to close the socket (http://msdn.microsoft.com/en-us/library/windows/desktop/ms741394(v=vs.85).aspx) From MSDN - "Note To assure that all data is sent and received on a connection, an application should call shutdown before calling closesocket" Before you bind the socket, you can use SO_REUSEADDR for setsocketopt which will "Allows the socket to be bound to an address that is already in use" (http://msdn.microsoft.com/en-us/library/windows/desktop/ms740476(v=vs.85).aspx) Finally, look at this blog - http://blogs.t
open new TCP/IP socket or to handle socket data. It looks like that in most cases the problem occurs when total count of opened sockets reaches some magical number. MS writes that this limit is 3976 simultaneously opened sockets but it seems that on Win9x systems the real limit is much lower. Proxy+ uses permanently about 10-20 opened sockets (it depends on configuration, number of defined Mapped Links,...) and each client request allocates two sockets - one for client side and one for server side of connection. Because TCP/IP system doesn't free sockets immediately when they are closed (socket remains allocated for 240 seconds after application closes it) it is possible that system will report WSAENOBUFS due to lack of free socket resources. Solution: There are following articles in Microsoft Knowledge base: Windows NT/2000: http://support.microsoft.com/support/kb/articles/Q196/2/71.ASP Windows 95: http://support.microsoft.com/support/kb/articles/Q170/7/91.ASP Some users reported to us there is another solution for Windows 95/98/Me which solved the problem at all. Windows 95/98/Me allows up to 100 (default value) of concurrent TCP connections. It looks like when the number of connection reaches the limit 10055 error is reported. The solution is to increase the limit of simultaneous connections. You can do it by changing/creating value of the key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\MSTCP\MaxConnections If you will create the MaxConnections variable key use STRING type for it (early Windows 95 used DWORD probably). Set the value to 300 for example, restart the Windows and check whether 10055 problem disappeared. There is MS Knowledge Base article which describes the meaning of MSTCP registry entries: http://support.microsoft.com/support/kb/articles/Q158/4/74.ASP Notes: You can obtain a list of opened sockets (including sockets in close state) using netstat utility: Run DOS Prompt and then type: netstat -an | more when you will press the Enter key you see a list of opened sockets (you will see big number in *_WAIT state probably).
