error discarding packet

[Gary Gatten]

There are some switches in top (differ by platform) that will show you individual threads and their accumulated CPU time, current CPU util, etc.  Such as:

Top -p "YOUR-PID" -H.  You MAY have to start the app (FR) in gdb to figure out what thread is doing what (sometimes the app will log when threads start and what they're doing - but sometimes not).  A more seasoned SysAdmin may have an easier / better solution, but this method has proven invaluable to me when trying to troubleshoot multithreaded apps and determine which thread is using most memory, cpu, etc. and what functions that thread is doing.

i'm using 15 threads and monitoring on top, the max server load is 2.0/3.0 

2009/12/23 Gary Gatten <Ggatten at waddell.com>

Isn't there some guidelines in the conf files for these?  Generally you want as few threads as possible to service the load.  How volatile your connections are, are more important than the max number of possible connections, and only you know this.  Perhaps start with 10 threads and monitor with top now and then.

 The default configuration.

 That is not the default configuration.

 You have changed the server to *slow it down*.

 Why?

 If this issue is so important for you, why are you so insistent on
ignoring *all* help that you get on this list?

 A basic install of FreeRADIUS + MySQL on a normal system will get
100's of auth/s with 10's of 1000's of users in the DB.  If you can't
get that, it is because *you* have broken the configuration.

 Don't break the default configuration.

 Follow instructions on this list.

 It's really *not* that difficult to make the server work.

 *Stop* editing things you don't understand.

 All you need to do is to *stop* breaking the server.
