lots of records = live accounting has reached a block 

> i didn't comment out the "radutmp" line, because i need to have a n accounting

yes - but HOW do you DO accounting? you say you need to have radutmp - but how do you use
that file - are you sure you use it and not eg SQL accounting?  if you have got to a stage
where the accounting requirements cannot be met in real time, then you need to look at migrating
to using eg detail file 'just out of live time' accounting - or moving the accounting off the
live auth server and using eg decoupled accounting, or proxy to home server buffered accounting..
or even move to a more efficient method such as buffered-sql . 

however, the issue may also be caused by some other local issue - such as network contention
(if you proxy requests), resource starvation (host is doing more than just the radiusd and doesnt
have enough resource - be that CPU or disk access - to do its job), or, if virtualised, the host
may not have all it needs because some other virtual host is stealing the cycles now


..or you've finally encountered a bug. does this happen with latest release (2.1.12)?
