Hello all,

I am continuously getting this error message on my
/var/log/radius/radius.log file:

Mon Sep 28 18:26:55 2009 : Error: WARNING: Unresponsive child (id
1094719808) for request 24026 (in component accounting module
rlm_exec)

In effect, I got a timeout on account start and stop which resulted
that even the user is able to authenticate and authorize, accounting
side fails.

I have attached my /etc/raddb/radiusd.conf for more information.

My RADIUS machine has the following information:

And the output of my "show full processlist" on my MySQL server and
the "lsof -ni -P | grep mysql | wc -l" says I have 100 rows.

The header output of my mytop command says:
