I´m open to other ideas how to exchange this information. But you will
agree this problem needs to be looked at.
Clearly there is a correlation between memory an connections. Please refer
to:

BUT
1) as you can see on this pictures the system "dies" once at 19 k
connections. But two times later everything is fine at more than 20k
connections
2) At every time (execpt the blank obviously) there is plenty of free
memory.
3) Our machines operatate limited to ~320 - 400 Mbits and memory has never
been an issue in 1-2 years
4) How do we explain the tor process just uses 400 Meg of memory each (see
arma comment above)
Something is not adding up here and this is what we have to find out.
