I discovered on my system (Smokeping 2.6.8, RHEL6, Apache 2.2, mod_fcgid 2.3.7) that Smokeping CGI procs became orphaned on both Apache restarts and graceful/reloads.
2506 ? Ss 0:32 /usr/sbin/httpd.worker 25417 ? S 0:00 \_ /usr/sbin/httpd.worker 25530 ? S 0:00 | \_ /bin/sh /opt/smokeping-2.6.8/htdocs/smokeping.fcgi 25531 ? S 0:01 | \_ /usr/bin/perl /opt/smokeping-2.6.8/bin/smokeping_cgi /opt/smokeping-2.6.8/etc/config 25418 ? Sl 0:00 \_ /usr/sbin/httpd.worker 25419 ? Sl 0:00 \_ /usr/sbin/httpd.worker 25420 ?

S 0:02 /usr/bin/perl /opt/smokeping-2.6.8/bin/smokeping_cgi /opt/smokeping-2.6.8/etc/config [...] Connecting strace shows that FastCGI sends a TERM signal to the smokeping.fcgi process (25530 above) but it's child 25531 doesn't get any signal and joins the growing list of orphans. (and no, not caused by SELinux.) Fix: changing smokeping.fcgi from the .dist ... #!/bin/sh /opt/smokeping-2.6.8/bin/smokeping_cgi /opt/smokeping-2.6.8/etc/config to: #!/bin/sh exec /opt/smokeping-2.6.8/bin/smokeping_cgi /opt/smokeping-2.6.8/etc/config ... resolves the problem for me. I suspect the "exec" should work in all cases (regular CGI too). Anybody else see this behavior? Eric
