ZBX_TCP_WRITE failed when using proxy

[maxxer]

hi.
I'm having a problem with services autodiscovery and Zabbix proxies. When the agent is ready to send back the result I get this error in debug:

Process listener error: ZBX_TCP_WRITE() failed: [32] Broken pipe

The problem happens only with proxy, because the same configuration item checked directly by the Zabbix server works great. I'm using Zabbix 2.2.8.

This is what I find in the agent log:

   577:20150107:145055.073 listener #1 [processing request]
   577:20150107:145055.074 Requested [zimbra.discovery]

        ]

   577:20150107:145103.630 listener #1 [waiting for connection]

The script execution takes several seconds and it's normal, I added "Timeout=15" in my agent config so it should not be a problem.


And in the proxy log:

  6634:20150107:155058.789 Zabbix agent item "zimbra.discovery" on host "webmail.domain.it" failed: first network error, wait for 15 seconds
  6637:20150107:155116.790 Zabbix agent item "zimbra.discovery" on host "webmail.domain.it" failed: another network error, wait for 15 seconds

I could't find what parameter is wrong. Any help is welcome.

I forgot to say that proxy (sqlite) and agent run on the same machine, so there should be no network glitch, and all other checks/discovery works fine.

thanks

It's not a Zabbix problem. It's TCP connection problem. UTFG: "tcp broken pipe error"
For example:

thanks for your useless answer, in fact it was a proxy issue, which was probably getting tired of waiting for the answer, and terminating the connection (thus the broken pipe).

Adding

Timeout=15

to zabbix_proxy.conf solved my issue.

[jan.garaj]

Thank you for your thanks for my useless answer.

I was just disappointed by your UTFG
cheers!

[jan.garaj]

That's not a reason to be sarcasm, if someone spent a times on your problem.
Sorry for UTFG, it didn't have negative meaning, but it's abbreviation to use google.

[maxxer]

apologies, but since it's not a kind abbreviation I decided I could answer ironically as well.

cheers

If I may....

Jan - I think it is the "F" in that which makes it offensive to some. I probably would have taken a bit of offense to it as well. Just as I would avoid telling someone to RTFM. While I may use these with someone I know, I would avoid doing so with casual acquaintances.

Maxxer - Jan is quite helpful to many on this forum and will often times go above and beyond what would be expected of a contributing member here to help solve someones issues . I am sure it wasn't meant in a mean way.

[maxxer]

thanks tchjts1, apologies to Jan.
I didn't want to offend either, it was just for fun, as I hope Jan mean the UTFG.

[jan.garaj]

No worry. I'll avoid it.
Why everyone know only one F* english word? (no answer is needed :-D) It has also polite meaning

All depends on what definition you go by.
And that's the thing. Nobody knows.
