> Have a server where Asterisk memory usage grow to ~8gb per 24 hours.
> I start Asterisk and after few minutes, I start to see memory changes.
> After some debugging, I've pinpoint the issue to Calendar modules and if I remove all res_calendar_* files then memory usage is normal.
> I've rebuild Asterisk with MALLOC_DEBUG and DONT_OPTIMIZE ..
> Here a partial log of valgrind started with :
