Hello,

Quote:

If I do a copy of several GB on the HN the VPS becomes unresponsive.

Here you did an I/O intensive operation. Could you possible conduct an experiment which involves not I/O but CPU intensive task just to narrow down our assumptions?

Quote:

Also I can see that the VPS receives the SIP messages over the network, but Asterisk stalls and does not process the call.

Is it possible to find out the state of the problem task for example via top? And also cat /proc/$PID/wchan, where $PID is Asterisk's PID?

Does Asterisk became responsive when copying process on the HN is finished?

sysctl: error: unknown error 1 setting key 'kernel.sysrq'

I think you shouldn't worry. That means that the process inside VE tried to tune sysctl which prohibited to do inside that VE.
