Hello,
I'm wondering if anyone experienced similar issue where Wordpress application with higher viewer volume is hanging in unexpected moments. As far as I know website is returning 500 error. w3wp and php-cgi processes for this website are working but not returning any website content. To fix this situation w3wp process must be restarted/killed (which kills also php-cgi processes) and after this operation website is up and running again. I've experienced this on multiple systems in various PHP versions in total not related Wordpress installations which are using caching plugins. Any thoughts? I'm wondering if this could be caused by WinCache plugin.
Thanks
