Hi all,

I have been asking this in October 2008, while using 2.0.4

I have not been able to change the version, as it was productive and you
guys are doing such a great job, that this has been my only real problem
with FR (even if it might not be FR problem, than a problem of some used
libraries).
Thank you all.
We set up a script, which restarted FR every 2-3 hours, which certainly has
its drawback.


Now it is time to setup a new system and I'm testing 2.1.6 for some weeks
now. 

I still see the memory consumption rising over the time
Output from top every 5 Minutes:
SIZE/RES
16M/13M
34M/32M
53M/51M
71M/69M
...it rises about 3-4 MB per Minutes.

I read about some issues and tried 2.1.7... still the same.

My Setup:
SUN X4100, 8GB, Solaris 10 5/09
Configured and installed incl. MySQL, but even if I disabled it for runtime,
the memory rises.

What would be a good start to debug this?
Is there a possibility, to see, which part of the running radiusd consumes
what amount of memory?

Thanks

Best regards,
Stefan
