Worst,
Mldonkey people had the tremendous idea to hardcode in their recent
version a initialization process of mldonkey which download 4 files on
savannah.nongnu.org via http.
As result, we seen load increasing day by day. And finally the problem
finally became obvious reading apache-ssl logs.
I forbidded access to the pages, wrote to mldonkey and they directly
released a new clean version, asking users to upgrade.
But the last time I checked, I found more than 60000 request on the
log of the day (apache-ssl logs are rotated daily).
Aside from waiting, I do not see what can we do. I reduce the
apache-ssl MaxClient value, I shutdowned many services for a while
(apache, crond) to get back a normal load, Loic was even forced to
reboot the server due a to hard disk failure (and remount of / in
read-only).
There's no much things we can do about.
We cannot identify mldonkey clients as some versions return "wget" as
UA.
