I guess so -- it happened again this morning when a moderator was approving some
posts, the server go a unbelievable high load: it took me about 30 minutes to
get into a telnet session and issue a shutdown :(
Everytime a post is approved, the connection stalls exactly 15 seconds (which
happens to be exactly the timeout of the lockfiles in mailman)... usually when
i had to do a shutdown, i have to replace ~mailman/lists/list-name/config.db
with config.db.latest because it has become corrupted ("no such list")
anyway, the server also handles mail and is supposed to be up 24h a day and i
hope i can fix this soon cause this is getting unworkable :(... and this way i
never get a cool uptime :)
