/proc/sys/fs/epoll/max_user_instances=128 considered harmful

2009-01-07 Thread Joe Orton
The F10 kernel has /proc/sys/fs/epoll/max_user_instances set to 128 by default. Apache httpd uses one epoll fd (instance) per child process, so this sets a hard limit on 128 children (i.e. 100 concurrent clients) out of the box. 1) shouldn't this be an rlimit so that we can bump it
