Michal Čihař <michal(a)cihar.com> napsal(a):
I had to temporarily shut down the demo server until I
will find time
what actually lead to enormous increase of PHP sessions and more or
less to DOS on this machine.
Okay, the culprit seems to be Sogou web
spider/4.0(+http://www.sogou.com/docs/help/webmasters.htm#07), it
generated few thousands of requests, each of them causing new session.
It did ignore robots.txt and tried to browse phpMyAdmin itself...
I've blocked it on firewall and demo server is back online.
