Failed remembering handle for proxy socket
Hello. I am running FreeRadius 2.1.6 and testing a huge configuration in the way that i am trying to open ~400 virtual servers on different ports. Have a file in /etc/raddb/sites-enabled with all the configuration (listen and virtual_server configs..) radiusd -X stops with the below error: snip... Listening on authentication address 192.168.199.9 port 22062 as server SERVER-22062 Listening on authentication address 192.168.199.9 port 22063 as server SERVER-22063 Listening on authentication address 192.168.199.9 port 22064 as server SERVER-22064 Listening on authentication address 192.168.199.9 port 22065 as server SERVER-22065 Listening on authentication address 192.168.199.9 port 22066 as server SERVER-22066 Listening on authentication address 192.168.199.9 port 22067 as server SERVER-22067 Failed remembering handle for proxy socket! Is this a limitation of my labsystem hardware, the operating system Centos 5.3, FreeRadius 2.1.6 or just not meant to work by design? If i lower the limit of virtual servers to approx. 200 the configuration works. Has anyone seen this error before?

OK. Will upgrade to 2.1.10. Thanks -- View this message in context: http://freeradius.1045715.n5.nabble.com/Failed-remembering-handle-for-proxy-... Sent from the FreeRadius - User mailing list archive at Nabble.com.
Upgrade to 2.1.10 did not solve the problem. I also tried increasing physical memory to 1,5 GB, but i still get the same error. Would be good to know where the limitation is.. I guess the configuration is not meant to be this way. Need to add more logic to the config i think.

It is not an "out of memory" error.

You are probably opening *way* too many sockets. I'm a little surprised at your configuration. It's rarely necessary to have the server listen on dozens of ports. Instead, select the virtual server by *client*. It's much simpler, and it scales to 500K clients. (Yes, this has been done) Alan DeKok.
hi, its an interesting test....why are you not using the latest release of FreeRADIUS (2.1.10 ?) for this work...you seem to be comfortable with the technology... is there a reason why you want so many virtual servers listening on the same IP address? It seems a strange design - surely policies and unlang within the server could operate the same scheme more efficiently? alan

2.1.6 has worked fine for us, until now when we need some new functionality. Alan Buxey wrote:

I believe you might be right Alan. It is not really the same IP-address that is necessary. We need a policy per port. If you saw my earlier post with user-name conversion titled "FR 2.1.6 add realm to User-Name before Proxy by listening port". This is what i am trying to accomplish. a port per customer where user-name conversion is done before proxy.. My unlang skills are not that good i am afraid. But if you can point me towards a simpler solution i would more than happy.
