I installed turpentine varnish cache, fpc on magento [url removed, login to view]
we have customized home page and showing 40products.
1 - Sometimes home page looks messy and showing 6 or 8 products
and we can fix only refresh fpc cache
2 - chkconfig bad organized, when we restart vps, site and varnish not working, I manually stop httpd service and some other and restart one by one with correct order. then site is working well
