hmmm... provide your conf file please, most of the time configuration
can be cleaned up by using _server_pool keywords (cf.
keepalived.conf.SYNOPSYS). But I recall a huge working conf with around
2000 realservers.
please provide a strace of the select() system call... select is great
with not lot of fd, but with around 1000 fds its ok ok... greater,
poll/epoll must be used (not yet implemented)
regards,
Alexandre
