[erlang-questions] Erlang 18.0, hanging erlang:memory(total)?

Hi folks,
is it possible that erlang:memory/1 can hang?

Today I had a unit test failing in the middle of its execution (it runs the 
same test over and over again and it was like the 20th time it was run). There 
was a timeout (>50s) in one process not being able to finish its message 
handling and erlang:process_info(Pid, current_stacktrace) is repeatedly 
showing the following stacktrace during these 50s:


The line in the dht_node_state module literally only calls 
erlang:memory(total) and creates a record with this info. Apparently, it never 
gets out of erlang:memory/1 :(

Thanks for your help
