Checking RadSec client certificate attributes with 'check_client_connections'

Hi, While checking RadSec client certificate attributes with 'check_client_connections', the radiusd main process usage increases up to 100%. I did some tests : same behaviour with just an 'ok' or a less trivial unlang check in the 'New-TLS-Connection' subsection. In debug mode, got no relevant logs, just thousands of lines containing 'Waking up in x.y seconds.' at the same timestamp as the CPU usage get high. How to fix this issue ? Regards, Arnaud
