Since last Friday, LISTSERV@OHSTVMA has abended for INSUFFICIENT STORAGE. I have LISTSERV set to REBOOT itself everyday at 23:59, and is running with 6m of storage. On one occasion, LISTSERV abended just 2 hours after an IPL of the VM system. Last night, LISTSERV REBOOTed itself at 23:59, and abended at 4:40am EDT. Does anybody have any idea what is going on? Perhaps a REBOOT should be done every couple of hours or so. Duane
