[SOLVED]Problems after update

[aspel]

First I had a cacti 0.8.6i everything be fine, after update on 0.8.7a I have some problems.

cron - 5 min
poller - 5 min

In logs I have these messages
12/31/2007 12:50:02 PM - POLLER: Poller[0] WARNING: Poller Output Table not Empty. Potential Data Source Issues for Data Sources: traffic_in(DS[17]), traffic_out(DS[17]), (DS[28])
12/31/2007 12:50:01 PM - POLLER: Poller[0] NOTE: Poller Int: '300', Cron Int: '300', Time Since Last: '301', Max Runtime '298', Poller Runs: '1'

What could be the problem?

I install cacti-plugin-arch and everything fine. I think problem was with a poller.php
