I've been running Pligg 1.0.0 for a while now but every once in a while it overloads my shared hosting. Their tech support says that "Your script is not terminating properly, and the processes started by it do not exit. " and this usually pertains to index.php or 'submit.php'. They have to manually kill the process to get it running again. How can I fix this? I am not ready to upgrade just yet, I need a temporary solution before I migrate to a newer version.
