I have nginx setup as a load balancer to three servers. Is there *any* reason a request would hit the log file more than once unless there were actually more than one incoming (from the internet) requests?

For example, if one of my internal servers is down or slow and a proxy timeout setting is reached, would that cause nginx to log twice to the access log? Would there be any message about said occurrence in any error or other log?

Thanks,
