If you are spawning processes and aren't waiting (or don't want to wait/watch) for them to complete (either by waitpid or another method) you can use `$SIG{CHLD}='IGNORE';` [download] to explicitly ignore SIG_CHLD signals. This will precent zombie processes from being created. (code taken from Perl Cookbook). Les Howard www.lesandchris.com Author of Net::Syslog and Number::Spell	[reply] [d/l]

No... if you don't catch it, it's merely ignored. But what's your real question? Why would you be thinking about SIGCHLD? -- Randal L. Schwartz, Perl hacker	[reply]

You dont need the worry about SIGCHLD as Randal said. You probably should include either a wait or a waitpid function call, so your child process does not become a zombie. See another discussion on forking	[reply]
