Subject cgi-bin Zombie proccesses [possibly OSX related question]
Date Wed, 10 Apr 2002 08:02:02 GMT
Okay I noticed under my own extremely bizzare situation a possible problem.

I have a cgi-bin proccess that is tring to connect with a socket to a 
session container type proccess. It actually is using a globally capable 
Portable Distributed Objects (PDO) System I built (because OSX failed to 
make NSConnections work correctly, or work at all from inside the apache 
cgi-bin, [unlike it did in OpenStep ... six months later Arrghh]).
This one I made is global as I said, it actually uses a Hub Server on a 
certain port for getting names registered for the PDO system to work.
The point ...
Well I made it so each registered proccess has a secondary thread that 
maintains the registration with the hub, and so if you kill the HubServer 
process, it will restart it.
If the cgi-bin connector finds the Hub unconnectable first it starts the 
HubServer. This is part of the Connection Framework's basic shared 
functionality.
The problem ...
When the cgi-bin process starts the other process with nohup (No Hangup) 
[and I redirected the output via something like 'nohup HubServer 2>>& 
logfile'], the cgi-bin process becomes a ZOMBIE process ... it hangs around 
until the child is terminated! (I do not want it to do that!)

Unfortunately the Browsers hang searching for the end of the process.
In the case of OmniWeb it Displays no picture in the case of an image being 
returned (banner system), and hangs locked out jammed (reallly bad the 
worst). In the case of Netscape the image shows but the page download 
animated icon shows it is still busy.
I believe that Apache should be responsible for letting go of ZOMBIE's in 
the cgi-bin. What can anybody say about this? Is this a Bug? Should I inform 
Apache about the Bug and where to I sent that message? (An email address 
please?)
