No buffer space available cherylnm Nov 27, 2006 12:43 PM I have a server problem that I cannot figure out.

Reason: No buffer space available (maximum connections reached?): JVM_Bind When the error happens, it is not serverwide. Some pages are still available (maybe those that do not run queries? very difficult to check). CF mail stops sending and just puts everything in the undeliverable folder. Our payment processing tag reports a "failure in cryptographic library" and will not process payments. I am able to access the DBs directly through SQL Enterprise Manager and run queries. This last time, I tried to just restart CF service by stopping it then starting it, but the server said it could not restart the service. Res

[closed] up vote 2 down vote favorite I have three servers running Windows 2003 https://forums.adobe.com/thread/196231 with ColdFusion 9 (JRun 4) and ColdFusion 10 (Tomcat 7). A few times a week one of the servers gets socket errors all over the place: javax.mail.MessagingException: Could not connect to SMTP host: 192.168.1.3, port: 25; nested exception is: java.net.SocketException: No buffer space available (maximum connections reached?): connect and SQLException while attempting to connect: java.sql.SQLNonTransientConnectionException: [Macromedia][SQLServer JDBC Driver]Error establishing socket to host and port: 192.168.1.11:1433. Reason: No buffer space available (maximum connections reached?): connect. and java.io.IOException: http://stackoverflow.com/questions/15640039/why-no-buffer-space-available-error-when-i-have-enough-ports Socket read failed at org.apache.coyote.ajp.AjpProcessor.read(AjpProcessor.java:323) Of course I have been searching Google and Stack Overflow for this error and I have tried many possible fixes. Such as the MaxPorts registry value. The problem I have is that these servers are not running out of ports. They have plenty. I've been using TCPview and netstat (even CurrPorts logging all TCP and UDP changes to file) to analyse the situation. But every looks fine. At no time are there more than a few hundred connections in- and outbound. Also, not all outgoing requests from the servers throw a socket exception. The websites running on these machines are reachable but sometimes (it seems random) a visitor gets the aforementioned socket errors. Connecting to these machines with RDP is not a problem and doing a ping or telnet call from these servers to somewhere else is never a problem. So, how can I be running out of ports when I have enough ports? java windows networking tcp coldfusion share|improve this question asked Mar 26 '13 at 14:48 Jan Brünemann 1399 closed as not a real question by EJP, nneonneo, Frank van Puffelen, plaes, p.s.w.g Mar 27 '13 at 1:05 It's difficult to tell what is being asked here.

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 conne
