Václav, That is good to know that you have also experienced better performance with patch from ticket 492.
I am replying this e-mail just to endorse your scenario. I have already been in the same circumstance of Varnish getting stuck after a bigger wave of simultaneous users. What I did to solve the problem? Put more machines. That would be great if we find the answer for this problem together. About the unpatched version, I was not able to see if freeze like the patched one because it hangs with another error before we can reach a maximum of simultaneous users, like in this report: http://varnish.projects.linpro.no/ticket/573 This problem by itself was what lead me to make this patch/port for epoll acceptor, since I use linux.
