Hi Alan, ============================================================================== We are using Radius 2.2.1. Can we fix the child hung by putting any patch ? For my understanding of Radius server behavior May I know the possible root causes for "Child is hung" ? In our scenario, I believe that when backlog is growing, some point of time each request faces "max_request_time" - out so it is giving child is hung message i.e. the request is in queue but no worker thread has picked it. ==============================================================================
Please let me know whether it is a good idea to set the max_request to 3000 so that radius server will not face "child is hung" and no need to restart the server to resolve the same.
It doesn't solve the problem. It just delays the problem. May I know why we will not be able to solve and it will delays the problem please? ============================================================================== On Fri, Nov 21, 2014 at 10:28 PM, Alan DeKok <aland@deployingradius.com> wrote:

Radius server take radius request and only for accouting request (not for access), it will send it to another module via TCP/IP (local server) and the module to convert it to diameter request to send it to IN server. The same module will response to Radius server for any response comes from IN.
So Radius server can support only 100 TPS at max.
Then don't send more that 100 TPS to the RADIUS server. Otherwise, it won't work.
Because when radius server faces "child is hung", we need to restart to bring it normal.
For v2, please try the v2.x.x branch. I've put a patch in which may help this.
