Putty says Network Error: no buffer space available, IE won't open any new connections but e.g. network drive mappings still work, even new ones can be established. netstat does not show more open connections that usual, ping and DNS lookups work fine.

It just happened to me in Win7 64bit. Chrome and Firefox stopped being able to connect to any web pages, windows file sharing stopped working, and WinSCP and PuTTY both gave errors that included the words No buffer space available. Oddly, Ubuntu 10 running under VirtualBox seemed to have no problem making new network connections - maybe it holds a number of network buffers in reserve. To find out what software is leaking network buffers, you need to close programs until the problem goes away. So I started closing programs and trying the WinSCP connection after each program I closed, but the error persisted. Once I'd closed every visible program, I opened Windows Task Manager with Ctrl-Shift-Esc and started killing invisible programs with the End Process button. Be careful - killing some things the system relies on can cau

java.sql.SQLException: Network error IOException: No buffer space available (maximum connections reached?): connect I was able to reproduce the error on my local windows 7 machine. this error is throw when the OS runs out of dynamic ephemeral http://serverfault.com/questions/131935/network-error-no-buffer-space-available ports. So we went ahead and increased the port range on our server until we figured out a way to troubleshoot the issue. but its not helping and every week to 10 days, we start getting the error. From the various testing, it looks like there could be process that is basically running wild and using up the ephemeral ports. by the time we log on and capture the netstat the number of ports https://social.technet.microsoft.com/Forums/windowsserver/en-US/157d8f12-66dc-4fb7-9014-c47e65019d2d/no-buffer-space?forum=winserverPN are in hardly 1000's. is there any tool similar to port reporter (compatible with windows 2003) on windows 2008? i tried the winsock event log but couldn't make much head way. i am open to any ideas on solving this issue.. thanks bharat Wednesday, June 02, 2010 3:41 PM Reply | Quote Answers 0 Sign in to vote hi amit, I think we have figured out the issue. we turned off the http and outlook scanning module on the anti virus that was installed on the server and after that we haven't seen out of buffer space issue on that server. The issue used to crop up once a month and we used to reboot the system. And it has been more then 2 months since the last out of buffer space issue on that server. links that helped us in pointing to anit-virus: https://trac.torproject.org/projects/tor/wiki/TheOnionRouter/WindowsBufferProblems https://trac.torproject.org/projects/tor/ticket/98 Thank you bharat Marked as answer by bharat.satya Monday, September 20, 2010 3:36 PM Monday, September 20, 2010 1:27 PM Reply | Quote All replies 0 Sign in to vote Hi, Thank you for your post here. What about the Sysinternal tool TCPView? It will show detailed listings of all TCP and UDP endpoints and the name of the process that owns the endpoint.

Replacing the cable may also help. Removing traffic shaping if it is enabled is also a good test. Otherwise investigate the traffic on the NIC and look for other buffer-related causes.

connections reached?): JVM_Bind" issue I hit this issue recently which occurred on only one windows 7 host. The error was caused by this hard to guess reason (http://support.microsoft.com/kb/196271). The default number of ephemeral TCP ports is 5000. Sometimes this number may become less if the server has too many active client connections due to which the ephemeral TCP ports are all used up and in this case no more can be allocated to a new client connection request resulting in the below issue (for a Java application): Caused by: java.net.SocketException: No buffer space available (maximum connections reached?): JVM_Bind at java.net.PlainSocketImpl.socketBind(Native Method) at java.net.PlainSocketImpl.bind(PlainSocketImpl.java:365) at java.net.Socket.bind(Socket.java:577) at com.sun.net.ssl.internal.ssl.BaseSSLSocketImpl.bind(BaseSSLSocketImpl.java:95) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.bind(SSLSocketImpl.java:45) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.
