ZBX_TCP_READ() failed error

[netwrm]

I am getting this error ons some of my hosts using Zabbix 1.4.4

I fixed this by restarting the zabbix agend on the host server. Was wondering what causes it.

I haven't gone and and read the source, but from experience it happens when the TCP link between agent and server has been created and is broken before the Server expects it to be torn down. It usually happens as one of two types from what I've seen either "Interrupted System Call" or "Connection reset by peer". The first "Interrupted System Call" happens when the agent takes too long to respond and an internal timeout counter in the server kills the link. I think the threshold is 30 seconds. The second occurs when the link has been created, the server tries to send data but the link dies for whatever reason.

This is one of the more common error messages you will find in Zabbix and at times one of the most frustrating to debug, and usually it comes down to one tiny little stupid mistake.

Just in case you are back already, the low level messages like this will be eliminated at some point. The messages do not provide any valuable information, they are confusing!

I would say don't get rid of it, but rather change the error message into something more meaningful. "Connection to agent took too long" would make for a much better error message for the timeout or "No reply from agent within X seconds."

I believe make the error messages more descriptive and the "silly" problems people post about will reduce greatly.

but that's just my 1.71 cents... damm dollar devaluation...

I fully agree with you.
