Newer Linux kernels provide reserved internals signals for LinuxThreads to use, and Apache should only be using SIGUSR1, but how confident are you that PHP grabbing this signal isn't going to break it in some environments? It may fix the problem in yours, but if it breaks it in many others that is something we need to deal with. ------------------------------------------------------------------------ [2010-01-10 21:45:30] tdfischer at fedoraproject dot org This bug is still around and can wreak havok for a drupal site that lets users submit content via machine-local mail.
