last weeks i have been working on a really annoying error and cant find my answer anywhere. Hope one of you could be of help, please see the issue and all info below...thanks!
For a couple of weeks I have now an annoying 324 error that pops up randomly on my multistore magento installation. It happens randomly and is there only for one minute or so. If there it is on all 4 frontends.The error says:
Error 324 (net::ERR_EMPTY_RESPONSE): The server closed the connection without sending any data.
main domain: www.top40zonnebrillen.nl
Magento multistore (4 front ends) version 18.104.22.168
dedicated server info:
Processor Name - Intel® Xeon(R) CPU X5560 @ 2.80GHz
Processor Speed (MHz) - 2792.920
server has more magento installations, but don’t have a lot of traffic.
The 324 error happens randomly, therefore it’s almost impossible to reproduce the issue.
Around the period the issue started we have done two changes to the installation, but don’t know if it is related:
1.) Changed one of the domains, from raybanspecialist.nl to rbspecialist.nl - also created a 301 redirect on the old domain using .htaccess file
2.) moved a 4th frontend from development to live server. This is still in ‘test’ modus for content purposes. One custom extension was added that includes a voting mechanism based on the users ip address, see http://ekotest.nl/kids/kinderkampioen.html
I have researched the fora, google and asked others and spend already a good amount on researching. So far have found this:
1.) google chrome browser issue, but also happened once in firefox
2.) Apache error, did a restart of the apache but did not solve the issue
3.) according to my hoster, database and server has no issues also the server logs have no errors. Probably be a programming error towards the sql connection
4.) went through all error logs, but no real issues are shown that could cause this (mainly about files that don’t exist)
