Comment 21 for bug 494476

Happening to me too. Several times on the 11th and 12th. May be triggered by load from outside. Looks like a synflood after an incident yesterday. Added mod_evasive, blocked a few bad bots, Reduced maxclients to 50 (prefork). No events since last night. https://www.bijk.com/p/2199b5ea shows yesterday's outage which will roll off tomorrow. I can grant access to someone who wants a closer look.

In my case, I suspect the events are associated with external web server load and are accompanied by dysfunction.This is my only server which gets significant traffic. The others are operating peacefully.

LAMP is my bread and butter. This is the "proof of the blood".
