Asterisk memory leak?

Memory leak with asterisk ?

I noticed this morning that almost all my memory was used (2gb !) I stopped the asterisk services and misdn services but the memory was still the same. Only after a reboot of the system did i have 1700mb memory free. But now I notice that it is slow climbing down to less memory . It goes about 1 mb per 10 minutes but it will not release this amount of memory anymore. So in a few more days my memory will be full again .
It does not take any swap memory and its measured with the free -m

Linux version Red Hat 4.1.2-14

[root@vcitamil001 asterisk]# asterisk -r

thanks mate,

Still strange that the memory is being “eaten” up without seeing it in the top or ps applications…

Will tweak my alerting system to reflex this

It does show up in top if you interpret the information properly. Basically you ignore what is reserved for cache memory. That shows up in top and most other memory statistics.
