upgraded net-snmp, polling stopped working, please help

[henryd31]

Hi, running FC3 system, I wanted to try the weathermap plugin and discovered I didn't have the gd installed. When, I used yum to install it and at the same time it upgraded my php. After that, poller was complaining about lacking net-snmp. Well, I upgraded net-snmp with yum,
but now in my cacti.log I get messy results, I see it complains as if hosts are not responding to snmp, but manually they do respond.

Ie:

No graphs are being updated anymore, all devices show "Down" status.
What else can I check here ?

[henryd31]

Forgot to mention, I can also go to a device and create new graphs,
yet when poller is running using cactid (I was running 0.8.6f, just few minutes ago upgraded to 0.8.6g to see if that would make a difference)
no graphs are updated, all devices show "Down" status, in the debug mode it shows hosts not responding to snmp, and graphs created with
running shell scripts are working properly. It would seem being totally related to the net-snmp upgrade, but I can't figure out why it works my hand, and in other cases like being able to get this info thru creation of new graphs. Any ideas anyone ?

Ok, I guess I should have known not to use the damn "yum"....It chose to upgrade my php with net-snmp, and this broke the whole thing. I manually removed the php and net-snmp packages. Downloaded the older
versions, installed, and what a surprise, the whole thing started working again. fyi, yum upgraded php to 4.3.11 and net-snmp to 5.2.1. I reverted
this back to php 4.3.9 and net-snmp 5.1.2.

Thanks !
