In OUT Traffic issue

In OUT Traffic issue

Hello,

I am having a problem, i am using netflow analyzer v 4.0.2 and its been working smoothly for last couple of weeks, now the problem is that after restarting the server it is NOT showing any OUT traffic on my interfaces and currently its showing wrong incorrect traffic stats on my link, mean to say my internet link is utilizing 1.9 MB traffic while netflow IN Traffic is stuck to 500-600 kb and OUT traffic is 0 bps. PLease tell me what has happened? before it was showing proper stats and was working absolutely fine. where could be the problem? please advise me at your earliest.

regards
Ali
