Description of my issue:
You have been so helpful in the past (and so knowledgable) that I thought I would ask you about a problem that I am having with a shopping cart site HarryChapinMusic.com . I don't have any evidence that it has to do with AdminTools but of course it is possible with the restrictions set there.
At the end of the VirtueMart shopping cart process customers cannot complete their orders- sometimes- because the firewall is receiving too many concurrent connections and shuts them out.
My understanding of the web server is that connections are kept open for an amount of time so they can be reused, if they are not reused they can stay open and count up until the number 5 is reached and then the firewall kicks in.
I can reproduce it at will, by doing a flood ping attack. Not that this is normal but it highlites the problem.
I think the limit of concurrent connections needs to be increased but the host says that they have never had problems like this on any other Joomla site.
It has seriously effected the number of orders we are receiving.
Any ideas?
Thanks so much, Tim
