There are 616 files in the system spool and 2 files in the RSCSV2 spool. LISTSERV is automatically going offline and will stop processing reader files, as dictated by the SYSVARS variable "OFFLINETHR" which is described in LISTSERV SYSVARS and can be changed by modifying the LOCAL SYSVARS file. You can bring LISTSERV back online, if desired, by issuing an ONLINE command. It will, however, come back online automatically when the system spool goes below 300 files and the RSCSV2 spool goes below 2000 files.
