[OpenSIPS-Users] Scalability and radiusclient-ng

I have a couple of questions regarding OpenSIPS scalability.

If I understood correctly a single child of OpenSIPS is able to handle 1 transaction simultaneously? So if I have 10 concurrent transactions I need at least 10 children, otherwise transactions will wait for a free child to take care?

Second question is scalability of radiusclient-ng? Does radiusclient-ng able to take care of concurrent requests or it works sequentially? I noticed that it use .seq file to synchronize request. From my understanding it suggests that radiusclient-ng works with requests one by one.
I receive the following error at 10 cps:
13:42:57 y-dev5 /usr/sbin/opensips[10887]: rc_get_seqnbr: couldn't get lock after 10 tries: /var/run/opensips/opensips_radius.seq
Does it mean that acc_radius request failed? Is there any way to get it more robust?

Best Regards,
