We had this crap as well and tried to get folks to fix it - important sites just don't care and yes, we are usually talking broken web stuff here. Hard to tell their ISP to get them to fix it. I am asking myself if we can nuke it elsewhere, nothing obvious right off ? > o when it breaks, the software does successive guesswork back-offs until > it makes it through. the performance sucks big-time, the customer > thinks the isp is at fault, but the noc does not get called and the > real problem never gets fixed. Agreed. Regardless of what I mention above, nuke em, i.e. fix. Dave > randy
