Hey. My experience with Perl is that Parallel::Forkmanager can create "defunct" processes if you lock up in the forkmanager callbacks. And since you will want to use PF with perl to make it "cluster-aware", maybe you should look there. If the C and Java processes also get defunct... PF is likely not your problem. /P ej magpayo wrote: > I have a few questions about openmosix.
