Hi Arun, My suggestion for "Urgent Support" is to try this way > http://networkradius.com/freeradius-support/index.html p.s: FreeRadius 2.2 is from 2012... too old! At first, try to upgrade to 2.2.9 (latest from v2.2.x) or come to the v3.1.x/v3.0.x side of the force! []s -- Jorge Pereira On Thu, Nov 5, 2015 at 1:41 AM, <bbnlrad@bbnldevices.in> wrote:
Hi, I am new to radius, hence please forgive me if i am asking very basic stupid questions.
We have a production box having radius 2.2. it is talking to a mysql server 5.1. The broadband clients are coming in through mikrotik router 6x
From past a month a month we are seeing that the radius is getting into issues intermittently and does not respond. we keep seeing the following errors during that time. ue Nov 3 22:25:59 2015 : Info: WARNING: Child is hung for request 12221 in component <core> module <queue>. Tue Nov 3 22:25:59 2015 : Info: WARNING: Child is hung for request 11643 in component <core> module <queue>. Tue Nov 3 22:25:59 2015 : Info: WARNING: Child is hung for request 12795 in component <core> module <queue>. The connections on the db side is around
In the radacct table we see around 8 to 9k users online. the mysql database is running on a dual core with around 1% loadaverage and the user cpu is just getting consume around 12%. Based on this i do presume the db is running fine.
A small obseravtion from my team is that if the users crsossed around 10k the the issues starts.
Can somebody please do help me out as to what configuration needs to be done in the radius server for a large volume we have around 60k customers, what internal tweaking needs to be done on the radius server side. Also please help me out as to what recommendation needs to set on the db side too.
one the radiusd.conf file down below is what i see which is un commented max_request_time = 30 cleanup_delay = 5 max_requests = 2048 thread pool { start_servers = 5 max_servers = 32 min_spare_servers = 3 max_spare_servers = 10 max_requests_per_server = 0 }
sql.conf has num_sql_socks = 200 connect_failure_retry_delay = 60 lifetime = 0 max_queries = 0 nas_table = "nas"
the db has symbolic-links=0 innodb_stats_on_metadata=0
key_buffer=128M myisam_sort_buffer_size=128M sort_buffer_size=32M
innodb_buffer_pool_size=5120M innodb_log_file_size=256M innodb_file_per_table innodb_flush_log_at_trx_commit=2 innodb_flush_method=O_DIRECT
when we start seeing the errors in the adius logs, i have tried to login to the mysql from the radius server, it takes time to login.
The machine is a quad core with 8 gb ram
Your help is greatly appreciated.
Thanks Arun
