Nagios Support Forum

Hi
I'm using Nagios core 4.4.3 on linux red hat 7 env
with gearmad V.0.33

ON the worker Log I got a lot of these errors
worker error: connection_pool (GEARMAN_TIMEOUT) timeout occured while trying to connect -> libgearman/connection.cc:109

Someone could help me to solve/undertand this error ?

thanks
Emilio

Hello Emilio,

Just for clarification, are trying to set this up or was it working and now your experiencing this issue?

It looks like the worker cannot connect to the Gearman server. Did you open port 4730 on the Gearman server and set the IP address in the worker configuration file to the Gearman server?

Hi Benjamin

The situation is a little complicated

Nagios is installed on Virtual machine and this problem happens when i turn on
the nagios in a new vmaware environment (the same vmx file but in a different vcenter)

if I use gearman_top tools I see the worker connected but some times (every 4/5 sec) I got the error
error reading from localhost:4730: Interrupted system call

and in the worker log file I got
worker error: connection_pool (GEARMAN_TIMEOUT) timeout occured while trying to connect -> libgearman/connection.cc:109

The same worker some times make a connection and other time I got connection pool error

Could you give me any suggestion to debug the problem ?
thanks
Emilio

The assumption is that the firewall rules/ACLS/routes are not in place? Is it in a different datacenter? Different subnet? Did you re-IP?

Please have your firewall/security/network admins investigate the network paths, the firewalls, AND any IPS/IDS devices you have in your network.

Run this from worker:
- Where X.X.X.X is the IP of your XI sever (gearman job server)
Are you seeing dropped packets on the interface of the worker? What about the XI server?
Please attach your worker and job server logs so that we can review them.
