We're using Listerv-Lite on NT 4 and it normally works like a charm and
distributes e-mails at once.
Suddenly today it slowed down and there is now about 500 hundred .job files
in the spool directory.

Everything else seems to work fine.
LSMTP delivers all mail in time.
And there is enough processing power - LISTSERV only uses about 3%.
And the memory looks fine too.

Where do I look to see what is happening?

Thanks in advance,
Jesper.
