Radius crashing with "Failed adding event handler for socket: Too many readers"
Hello, I'm running Free Radius 3.0.13 on Redhat 7 and the about once or 10 times a day the service will "crash" (Exit with error code 1) with the error message "Failed adding event handler for socket: Too many readers". The only messages prior to Radius crashing are: Mar 19 21:37:34 radius1.acme.com radiusd[11344]: ... adding new socket proxy address 202.AA.BB.CC port 57158 Mar 19 21:37:34 radius1.acme.com radiusd[11344]: ... adding new socket proxy address 202.AA.BB.CC port 57158 Mar 19 21:37:34 radius1.acme.com radiusd[11344]:Failed adding event handler for socket: Too many readers Then systemd picks up the failure: Mar 19 21:37:34 radius1.acme.com systemd:radiusd.service: main process exited, code=exited, status=1/FAILURE Mar 19 21:37:34 radius1.acme.com systemd:Unit radiusd.service entered failed state. Mar 19 21:37:34 radius1.acme.com systemd:radiusd.service failed. Our configuration consists of about 157 home_servers and about 276 clients and two upstream proxies. The problem is that the program isn't leaving behind core dumps, I don't know how to / can't actually reproduce the issue, I can't leave the server running in debug mode as it is handling upto 1500-3000 requests per minute (every minute) and finally it doesn't crash everyday, but it does some days - sometimes upto 10x a day. Probably the only major difference is that we use 'src_ipaddr' directive throughout the whole configuration. This is because all packets are present via an Anycast interface (and obviously we need to reply to the packets from the same IP address). The issue seems to be similar to: http://lists.freeradius.org/pipermail/freeradius-users/2015-July/078835.html and GitHub issue: https://github.com/FreeRADIUS/freeradius-server/issues/1155 - But these issues got patched in August 2015... I have attached an obfuscated (and truncated) radius debug log. I had to truncate it because it would be 9000 lines before the first request is handled. Any assistance anyone can provide would be appreciated. Thanks Cam.

I'm running Free Radius 3.0.13
Upgrade to 3.0.16.
on Redhat 7 and the about once or 10 times a day the service will "crash" (Exit with error code 1) with the error message "Failed adding event handler for socket: Too many readers".
See doc/bugs. You can run it under gdb to see what the problem is. But realistically.. upgrade, and the problem will go away. It's not really worth our effort to debug issues which were found and fixed a year ago. Alan DeKok.
