[asterisk-users] High resident memory with 11.14.0 ?

[James Lamanna]

Also, how big does the cache in frame.c grow to?
I've recompiled with MALLOC_DEBUG on that server:

asterisk -rx "memory show summary"

....
1780466242 bytes (1780181594 cache) in    2352909 allocations in file
frame.c
...

Seems like a ridiculous cache.
