running Webserver Stress Tool. The IP stack can't create additional outgoing TCP/IP connections because it runs out of available socket numbers for the IP address(es) that you have configured in Webstress. This error occurs when your workstation cannot allocate new sockets. On Windows the default limitation is 5000 - 1024 open sockets (5000 is the default max user port setting and the first 1024 ports are reserved). You can increase the default maximum socket value in the registry: HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/Tcpip/Parameters and add or modify the MaxUserPort value. See Also Microsoft article: "When you try to connect from TCP ports greater than 5000 you receive the error 'WSAENOBUFS (10055)'" The Cable Guy article: "Windows TCP/IP Ephemeral, Reserved, and Blocked Port Behavior" Add comment Created on Feb 24, 2010 9:10:15 AM by Daniel Zobel [Paessler Support] Last change on Sep 1, 2015 8:07:43 AM by Erhard Mikulik [Paessler Support] Permalink Please log in or register to enter your reply.

and both ends must ACK (acknowledge) each other's FIN packets. The FIN packets are initiated by the application performing a close(), a shutdown(), or an exit(). The ACKs are handled by the kernel http://hea-www.harvard.edu/~fine/Tech/addrinuse.html after the close() has completed. Because of this, it is possible for the process to http://stackoverflow.com/questions/2399729/tcp-address-already-in-use-exception-possible-causes-for-client-port-no-port complete before the kernel has released the associated network resource, and this port cannot be bound to another process until the kernel has decided that it is done. Figure 1 Figure 1 shows all of the possible states that can occur during a normal closure, depending on the order in which things happen. Note that if you initiate closure, there error 10048 is a TIME_WAIT state that is absent from the other side. This TIME_WAIT is necessary in case the ACK you sent wasn't received, or in case spurious packets show up for other reasons. I'm really not sure why this state isn't necessary on the other side, when the remote end initiates closure, but this is definitely the case. TIME_WAIT is the state that typically ties up the port for several minutes after the process address already in has completed. The length of the associated timeout varies on different operating systems, and may be dynamic on some operating systems, however typical values are in the range of one to four minutes. If both ends send a FIN before either end receives it, both ends will have to go through TIME_WAIT. Normal Closure of Listen Sockets A socket which is listening for connections can be closed immediately if there are no connections pending, and the state proceeds directly to CLOSED. If connections are pending however, FIN_WAIT_1 is entered, and a TIME_WAIT is inevitable. Note that it is impossible to completely guarantee a clean closure here. While you can check the connections using a select() call before closure, a tiny but real possibility exists that a connection could arrive after the select() but before the close(). Abnormal Closure If the remote application dies unexpectedly while the connection is established, the local end will have to initiate closure. In this case TIME_WAIT is unavoidable. If the remote end disappears due to a network failure, or the remote machine reboots (both are rare), the local port will be tied up until each state times out. Worse, some older operating systems do not implement a timeout for FIN_WAIT_2, and it is possible to get stuck there forever, in which case restarting your server could require

Join them; it only takes a minute: Sign up TCP: Address already in use exception - possible causes for client port? NO PORT EXHAUSTION up vote 1 down vote favorite stupid problem. I get those from a client connecting to a server. Sadly, the setup is complicated making debugging complex - and we run out of options. The environment: *Client/Server system, both running on the same machine. The client is actually a service doing some database manipulation at specific times. * The cnonection comes from C# going through OleDb to an EasySoft JDBC driver to a custom written JDBC server that then hosts logic in C++. Yeah, compelx - but the third party supplier decided to expose the extension mechanisms for their server through a JDBC interface. Not a lot can be done here ;) The Symptom: At (ir)regular intervals we get a "Address already in use: connect" told from the JDBC driver. They seem to come from one particular service we run. Now, I did read all the stuff about port exhaustion. This is why we have a little tool running now that counts ports and their states every minute. Last time this happened, we had an astonishing 370 ports in use, with the count rising to about 900 AFTER the error. We aleady patched the registry (it is a windows machine) to allow more than the 5000 client ports standard,
