Hello freeradius support team, We have currently a new infrastucture using freeRadius 3 (freeradius-3.0.13-8.) on RHEL7.5. The infrastructure implements in front a layer “PROXY RADIUS” (not based on proxy.conf usage) allowing to forward requests either to a service RADIUS A or a service RADIUS B depending on the type of OTP. Service A handles/valids OTP A Service B handles/valids OTP B The infrastructure works as expected. However when a service disruption occurs on service B, the PROXY RADIUS is no longer able to forward the requests to service A. The PROXY is in a state stuck with the below error messages. Thu Oct 25 08:14:11 2018 : Error: Unresponsive child for request 5735, in component authenticate module perl Thu Oct 25 08:14:13 2018 : WARNING: (5735) WARNING: Module rlm_perl became unblocked :::::: Thu Oct 25 09:41:25 2018 : Error: Unresponsive child for request 5791, in component authenticate module perl Thu Oct 25 09:41:53 2018 : WARNING: (5783) WARNING: Module rlm_perl became unblocked How can we manage this kind of errors? Is there some parameters to release connections. I'm assuming the error indicates some sort of timeout in communication between rlm_perl and service B. Assuming this is a timeout-related error, what is an acceptable processing time? Thanks, Thierry - List info/subscribe/unsubscribe?
