[erlang-questions] Problem with erlang:memory(processes_used)

[Alexander Petrovsky]

Hi!

On Erlang v.17, the function erlang:memory(process_used) shows that summary
size on used memory near 17 (exa?)byte. The erlang application build on the
CI server as erlang release and then  rolled on the cluster.

CI server:

> erlang:system_info(system_version).
"Erlang/OTP 17 [erts-6.2] [source] [64-bit] [smp:4:4] [async-threads:10]
[kernel-poll:false]\n"

# uname -a
Linux ci.our.net 3.2.0-4-amd64 #1 SMP Debian 3.2.54-2 x86_64 GNU/Linux


Target server:

> erlang:system_info(system_version).
"Erlang/OTP 17 [erts-6.2] [source] [64-bit] [smp:4:4] [async-threads:10]
[kernel-poll:true]\n"

> erlang:memory(processes_used).

Can someone please help me with this?
