You'll have to give a little more detail.. What sort of client/child process are you talking about? A fork? A socket? A system call?? Maybe you can show the script, or the part of it that does this.. C.	[reply]

Again without detail it is very hard to give any advice but it might be worth looking into daemons and independent child processes. You might also be running a batch job in a CGI which would be better run as a daemon that processes a queue with the CGI pushing things onto that queue. But please can we have more detail. Hope it helps UnderMine	[reply]

It sounds like you want the processes to be associated but for it not to be a child-parent type relationship...?!?!?! just making sure i'm reading you right? can you please post some more info so we can help you Grygonos	[reply]

how i do for continue the script when the client abort conection? When i create a child process, it die when the parent process finish? You need to dissociate the child process from the parent in order for the child process to continue after the parent dies. You can do this by calling setsid which is part of the POSIX module. See the perlipc docs and search for "Complete Dissociation of Child from Parent" for an example of how to do this. - Cees	[reply]

`use POSIX; # ... if (!defined($pid=fork()) { # fork fails } elsif($pid) { # parent waitpid(-1, WNOHANG); # run code here } else { # child }` [download] or something like that :) .02 cLive ;-)	[reply] [d/l]
