Yes, I can only replicate this issue with command to start firewall.
Stopping firewall or other service commands don't have the problem.
Check Point firewall is a kernel application. 

Somehow select system call is interrupted and can't terminate the PIPE.
I don't know what interrupt it is, though.

I'll collect the full log and attach it here.
