008397:20070202:150637 Error doing snmp_open()

[manu_dbpur]

Hi,
Zabbix is contniously printing "008397:20070202:150637 Error doing snmp_open()" message in zabbix server log file. And server is not querying any data from the monitored hosts. Could some one please tell me what could be wrong.
I manually tried to do snmpwalk and it just works fine.

I am stuck now. Please help me.

Thanks,
Manu

restart zabbix server

Have you tried to restart the zabbix server?

I found the machine in a strange state after doing a bulk import.

A restart of the zabbix server daemon fixed it

Cheers,

Possible solution to this problem.

Hi All,

I came over the same issue whilst doing a manual upgrade from 1.3.2 to 1.3.5. I have manage to determine that this is caused by an empty DNS field on the host. This in turn within the checks_snmp.c file causes an empty item->host_ip field.

So, how did I correct it. I ran the following sql over my MySQL database.

update hosts set dns=host where dns = ""

which copies the hostname into the dns field.

I hope this helps.

Cheers,
Brian.
