Hi,
Looking for some help, currently running haproxy 1.4.8 sending front end
requests to several backends existing of JBOSS/Apache/IIS
We've noticed we are seeing thousands of PDVN errors per day, maybe 30K PDVN
errors out of 3 million hits daily.
We're not seeing any reason for these errors and no pattern as it happens among
all of our backends. We aren't exactly sure when they began and how long
they've been occurring, but they have continued steady since we noticed them.
Any insight would be greatly appreciated.
