I don't believe this is a known issue. It's possible that some kind of overflow is occurring in the library when you're specifying those large rate limits--they're typically one or two orders of magnitude greater than what I imagine are typically-set values. Are you sure it's not just a measurement error? Keep in mind that the rate limit is calculated only once per second. >>> Dan ------------------------------------------------------------------- List admin: http://cool.haxx.se/list/listinfo/curl-library Etiquette: http://curl.haxx.se/mail/etiquette.html
