Lighttpd

I'm modifing some fastcgi programs. When the fastcgi processes detect a new version, they will exit after finishing the request. But the new process wasn't started correctly, and I have to restart the lighttpd process. To make the proble explicit, I tried the following.

By

killall -TERM fcgiprogram

the fastcgi programs exit normally. But lighttpd doesn't restart them immediately.

If fortunate, fastcgi process will be started after refusing a few requests. This is not graceful, but it is bearable.

If unfortunate, lighttpd will be in a dead loop. In this case, At mod_fastcgi.c:2332, we have proc->state==PROC_STATE_DIED, but proc->load==1. The lighttpd process will
then take 100% CPU.

if (proc->state == PROC_STATE_DIED) {
     log_error_write(srv, __FILE__, __LINE__, "sd",
         "PROC_STATE_DIED, load=", proc->load);
}

tail lighttpd.error.log -f
2005-04-20 02:29:34: (mod_fastcgi.c.2332) PROC_STATE_DIED, load= 1
2005-04-20 02:29:34: (mod_fastcgi.c.2332) PROC_STATE_DIED, load= 1
2005-04-20 02:29:34: (mod_fastcgi.c.2332) PROC_STATE_DIED, load= 1
2005-04-20 02:29:34: (mod_fastcgi.c.2332) PROC_STATE_DIED, load= 1
