There are problems with eventport implementation, known for at least several years now, and these can be easily reproduced by running our test suite with 'use eventport' added to test configurations. If I recall correctly, upstream keepalive is not something important to trigger problems, any connection to an upstream is basically enough. Unfortunately, these problems are very low priority due to minor popularity of Solaris. Consider using /dev/poll instead, which is the default, well tested and has no known problems. The patch in question looks more like a hack to mitigate a particular issue the author was facing. It doesn't resolve the underlying problems though, and likely there are other issues as well. There are no plans to commit this patch. -- Maxim Dounin http://nginx.org/ _______________________________________________ nginx mailing list [email protected] http://mailman.nginx.org/mailman/listinfo/nginx
