Yes, exactly. And it's not really overload, the machine can easily
handle it, it's not loaded at all, even if customers do "interesting"
stuff. But it's just that the memory grows and never seems to shrink again.

Me too. I think I'll actually wait for 3.0.x or 3.1 and then make one
big upgrade. Night maintenance is not my favourite hobby so I'll make a
big step. I think the current 1.4.4 I'm running doesn't have any acute
problems or crashes so it's fine. :)

Thanks for your help and explanations (and ofcourse your work on Kamailio)!
