Hi,
Yes, you are right, a httpd process marks a fcgid process as busy and then
suddenly dies would cause the zombie issue.
I agree with your idea except: don't move process to error list, but a new
create process list (like zombie list?). Because a processs busy timeout not

mod_fcgid have to work on both UNIX and Win32, so the it pick a portable way to
make it done on both platforms.

Yes, split process control from mod_fcgid, merge proxy_fcgi(with
load balance) and mod_fcgid(with authXX support) is a good idea,
admins can use httpd as process manager, or 3rd party process managers as they
like.
But don't just make a patch to make mod_fcgid support TCP/IP, it's ugly...

A company need a "TCP/IP patch of mod_fcgid or alternative", and will pay

Hi, all
I took some times to setup a stress test for mod_fcgid, to see is there any
other concurrency bottleneck left, it seems fine to me.
I did a stress test with callgrind on mod_fcgid, this is the big picture:

httpd(or
mod_fcgid) either drop client connections or delay a while, there is no other

Another question. Is it necessary to call procmgr_init_spawn_cmd() from inside
the for loop ?
I took a brief look, it seems not necessary. I will move it out of loop and
test.

How about this:
1. procmgr_post_spawn_cmd() now return a status code from PM, so process
handler now know the spawn request is denyed or not.
2. if a new process is created, no sleep is needed.
3. if no process is created, sleep a while

But since someone said remove this sleep(), the server work fine without
bottleneck(Maybe he didn't notise the warm up issue?), so I thought remove the
sleep() is a good idea. But reduce the time of sleep() is fine to me too.
Any other idea?

Hi, all
Another question, does proc_wait_process() should update procnode->proc_id to 0
too? or else mod_fcgid may send a signal to another irrelevant process while
apache is shutting down? I don't follow up mod_fcgid for a while, I just took a
glance, maybe it's updated somewhere else?
