<div dir="ltr"><pre class="" id="comment_text_106">Hi,<br><br></pre><pre class="" id="comment_text_106">I have a question about process_info().<br><br>For process <0,477,0> below,
heap_size is 6765 words,
stack_size is 12 words and
memory is 40,149,752 bytes.
Erlang doc says 'memory' includes stack, heap and internal structures.
In this case, stack + heap is 4*(6765+12)=27,108 bytes.
Does this mean most of memory usage(about 40M bytes) are used
for "internal structures"?
What is "internal structures"???<br><br></pre><pre class="" id="comment_text_106">(I'm still using R11B-5 and I don't know it's specific to R11B-5 or not.)</pre><pre class="" id="comment_text_106"><br>
Thanks in advance,<br>Kinoshita<br>
