So you have 167 channels. There's a thread for each, with stack and all.

I'm not sure. It doesn't even mean the kernel has allocated those 
100MB to Asterisk. Recall that a memory block is only allocated on 
first use. And Asterisk tends to allocate lots of memory. Not all of it
is actually used.

The best way is to rebuild Asterisk with memory allocation debugging.
