------------------------------------

We have been starting to use this patch 1 month ago .
We have about 200 cisco ipphones which most of them are using BLF to monitor other extensions but we are facing a very bad issue which seems memory leak to me after about 8 hours asterisk memory usage gradually going up to 1 gigabyte and in 48 hours it is something around 8-9 gigabyte of memory.
Disabling the blf on extensions and restarting asterisk  correct the issue and asterisk memory usage never goes beyond 50-60 meg with around 30 concurrent calls.
So it seems related to the blf patch.
I have attached pmap log of allocated memory which has to many anon memory block which also can be indications of memory leak
Also attached top report .
If GDB trace is need i can provide.
