I advanced in my investigations. I found that run_init creates a virtual pty and when openca_start forks to go in the background the pty is destroyed and the SIGHUP is sent (by the kernel ?) to the remaining processes. Here is my second problem. When I run "run_init nohup /etc/openca/openca_start", I get an "OOPS" from the kernel (attached). It may be easier to catch the SIGHUP in the OpenCA server. Does anybody know how to do this ?
