we run listserv on a Solaris machine. I was wondering does anyone know where the default setting is that listserv uses to scan the lists and pick up things like the probe dates. Basically I want to force a probe and do some trouble shooting without having to wait another day, is there a way to force it. I was thinking that If I modify the time that listserv does a scan of the lists for header variables then I can at least get it down to the hour. Kevin.
