dedicated-hosting

I'm hosting with MediaTemple on a (dv) Dedicated-Virtual 3.5 server. My site consists of a Wordpress blog, some custom PHP pages (nothing too intense), and I server 500-700 unique visitors per day.

Despite my pretty modest numbers, I suffer from regular Apache crashes on account of QoS Alerts, mostly flagged as "tcpsndbuf".

MediaTemple support -- usually tops -- has been pretty useless on this matter. I'm looking for answers as to how/why this is happening, advice on how to stop it. My website is a good portion of my livelihood, and downtime equates to lost income.

Any and all help much appreciated.

Could someone briefly explain how to use QoS on Cisco ASA 5505? I have the basics of policing down, but what about shaping and priorities? Basically what I'm trying to do is carve out some bandwidth for my VPN subnets (in an object-group called priority-traffic). I've seen this Cisco QoS document… >>> More
