SolarVPS. [UN]managed Support Quality Unacceptable To Me

I have very sad experience with solarvps and their support quality these days. I'm their user for over year now. Minor problems appeared rarely, but in those cases support reacting time and quality was simply excellent.

Now something wrong happened with them. To problem ticket, which priority is defined as emergency, they answer after 4 hours. Now i'm waiting for last answer already 11 hours.No answer till now. And server is not usable, our customers ar ready to eat us alive. It's going third day as we suffer from problem.

Ok, lets say their support staff is unable to solve this complex problem. But they should at least inform customer what is done to solve problem, what means are used and what's the current situation and problem solving progress. At first problem day they used to reply godaddy-style short zero-valuable comments, that have nothing to do with problem essence and solution. They simply don't try (or unable) to understand problem deeply enough.

This message to forum has mainly two targets. Primary is to get problem solution from all of you, who may have experienced same problem as me, since i already lost my hope to get problem solution from solarvps. Second - to kick *** solarVPS a bit for poor service quality.

And here is the problem.

VPS system: windows OS, 384mb of ram (venusX package).

As soon as i start apache server, or IIS server, or whatever server that is listening to port 80, same moment TCP connection count (measured by windows 'performance' tool) rises to more than 300, usually 600. Then all http requests are rejected, website is completely down. It is notable, that problem is clearly not caused by heavy http server loads. Problem appears on even low load. Stopping http server causes connections to fall to normal level, nearly 0. Starting again suddenly causes problem again. Connection count jumps rapidly to >300.

This problem appears about 30% of all time. There are periods problem does not appear, server functions normal. No problem regularity found.

It seems that connections are stuck at OS or physical level, they are not even handled by apache. Apache logs show no or little activity when problem happens, CPU usage is very low. Only very small part of requests are passed to apache. Others are just gone, although large amount of connections are shown by system. Seems they are somehow 'hung' and stay too long not disconnected.

When trying to reach website through browser, firefox says 'connection interrupted' at same moment. This again shows that requests are not even processed by apache. In case of heavy load 'time out' would appear after several seconds only.

At early stages of problem i suspected two causes: apache server software problem or DoS attack. Both of these were denied. Apache was reinstalled (and IIS, lighthttpd 'causes' the same problem too). DoS as cause was denied too, as traffic does not seem suspicious.

At this moment i do not know what to suspect, but its almost clear it's solarvps problem, not mine. As long as they did not deny it and got full understanding of problem. I could suspect virus, making DoS in their network, router physical disorder, what else? Anyway their problem, not mine. But his becomes my problem, as i have no service for third day.

I do not blame solarVPS for problem. Problem is realy mystical and interesting, it may happen to anyone. I just say that their support reacting time and quality is pathetic in this situation. And i miss adequate work to find problem cause.

Anyway they have work around to solve problem - move my whole VPS account to another physical server. But they don't answer about this.
