[SR-Users] removing stuff

Hi, This concerns third party tools...I suspect. First - I run Kamailio 1.5 and use Siremis to calculate the calls (actually just the stored procedure and cron job defined, not the interface). I have earlier been messing around with CDRTools and radius, but I don't use these anymore. However, they seem to still be generating lots of data on this server and overloading MySql - so I really want to get rid of them. Specifically are my radacct and sip_trace tables in MySql getting huge, and keep being populated...and I want to stop this 'madness'. What do I do to stop/remove this? without putting the current installation at risk) Thanks!! //Anders
