Hi

We are using radiator (on linux) to collect accounting data from Cisco WISMs 
(wireless infrastructure).  I have verified that the accounting data is being 
received by the radiator machines but a fair portion never makes it to the 
database.  Looking at the stats I see that there are a large number of drops 
during peak times.

I am trying to work out what is causing the drops.  CPU is sitting at well 
under 5% (mostly %1) the back end database is hosting many other databases that 
are not experiencing problems.  

I would really like some hints as to where to start diagnosing this issue.  I 
suspect that the issue has been there since the system was installed.  These 
machines were originally meant to do the authentication as well as the 
accounting but at go live got these same problems under load and it was decided 
to switch authentication to MS radius.

I am a security analysis with a lot of UNIX/Linux experience and I have root 
access to the radiator boxes (4 of them).
