Hi After installing redhat kernel 2.4.20-20.9 I started to get this messages in the kernel log: application bug: cron(4829) has SIGCHLD set to SIG_IGN but calls wait(). (see the NOTES section of 'man 2 wait'). Workaround activated. I have unmerged vcron and now Im using dcron to workarround that problem. Can some1 look into this and maybe get a patch for vcron ? (to me it seems to be more of a vcron problem then a redhat one).

You heard the man, he said it's more of a vcron problem... And as there isn't a clear maintainer, bouncing back to bug-wranglers
I'm not sure what to do with this. This only happens on the RedHat kernel. Ironically, it appears we've got RedHat's SIGCHLD patches, at least when I compared it to the rawhide rpm. It doesn't really hurt anything, since ignoring SIGCHLD, and then doing a wait() acts like SIGCHLD isn't ignored.
Redhat-sources has been removed for a while, and this only happens on that kernel.
