 Description   

Not sure what is producing this error message: "timeout while executing a shell script" when polling system.uname and system.hostname on a heavily-loaded server. All other agent parameters respond fine with no loss of data. Cannot filter on this message in the trigger expression using, for example:

{BB_RenderServer:system.hostname.diff(0)}

>0 &

{BB_RenderServer:system.hostname.regexp(*timeout*)}

=0

What is issuing this message - agent or server? It would seem that agent is. Are these the only agent builtin parameters that read via shell script and if so, why? I would rather not increase agent timeout unless it's the only way out.

Yes, this message produces agent.

You can try zabbix 1.8.11. It runs with a default scheduling priority instead of older version which has hardcoded priority 5. See ZBX-4564 for more details.

as per previous comment, assuming that default priority change should help with this problem. please, reopen if it is still reproducible with the latest version of the zabbix agent, thanks

I'm having the same issue with 1.8.13 agents on a bunch of linux based NAS :

Linux <hostname> 2.6.32.12 #2228 Thu May 10 02:19:28 CST 2012 armv5tel GNU/Linux synology_88f6281_109

Load is near 0, about 99%CPU idle, no gaps in data collection for these hosts .

Will be fixed in ZBX-5616.
