error doing curl_easy_perform: Server returned nothing(no headers, no dat)

[cloudmafia]

Hi,

I'm experiencing issue with web scenarios, it seems like curl is crashing but i'm not sure about it because i read on bug system that it was bug with previous version of zabbix...i though it might be bug of zabbix so i re-installed zabbix with recent stable release, details are as follows -

Zabbix proxy previous version - 2.0.2
current proxy version - 2.0.5
curl version - 7.19.7
OS - CentOS 6.3
proxy logs:

zabbix web scenario step "abc.com" error: error doing curl_easy_perform: Server returned nothing (no headers, no data)
 web scenario step "xyz.com:xyz.com" error: error
 doing curl_easy_perform: Timeout was reached

This is major issue with zabbix when it stops working and zabbix starts sending unreachable mails and spams mailboxes with false alerts...

Please help me to fix this issue and let me know if more information is required.

Thanks
Neo

Solved- error doing curl_easy_perform: Server returned nothing(no headers, no dat)

I think i got the solution, If someone experiencing the same issue then just increase Http pollers in proxy configuration file...

StartHTTPPoller= (Default value is 1, you might not find StartHTTPPoller in proxy configuration but you need to add it)
You can value between 0-1000

This issue occur because of load on http poller process so by increasing http poller we could solve this issue.

Cheers!
