Web Scenario - error doing curl_easy_perform:Srvr returnd nothing(no header,no data)

Hi,

I am having issue with web scenarios, i am monitoring web URLs since more than 6 months but suddenly experiencing issue with Web scenario...

log - 1704:20130313:092200.879 web scenario step "abc.xyz.com/pageOnline3:abc.xyz.com/pageonline3" error: error doing curl_easy_perform: Failure when receiving data from the peer

1749:20130313:092600.900 web scenario step "www.xyz.com:www.xyz.com" error: error doing curl_easy_perform: Server returned nothing (no headers, no data)

Don't understand whats happening, every 5 minute all urls getting down and getting up in less than 2 minute..

even upgraded version of curl from 7.19 to 7.29 and i'm using centOS 6.3...

Please help me to fix this issue, i am just stuck with this issue and unable to resolve it.

Tried fixing it but nothing worked and finally recompiled proxy. but still don't know why it happened...seems like curl was crashing.
