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.
