Hi All
I seem to be experiencing an intermittent fault with the utils http_query() method. We are implementing a routing and white list component that is accessed via a REST api, however i have observed several occasions where this is logged: Jan 30 16:04:17 vs-kam-prod02 /usr/local/sbin/kamailio[13184]: ERROR: utils [functions.c:149]: http_query(): failed to perform curl (28)
The indicated error number (28) seems to suggest a timeout is occurring with curl, however examining a capture of network traffic when this happens shows that a http request is not sent from the server to the destination at all, usually attempting a second call results in everything working correctly.
As stated its intermittent in its nature and so I cannot reliably trigger this issue, other than through sheer repetition, so any ideas as to what could be causing this issue would be gratefully received,
What happens if you run the daemon in foreground / high verbosity ? Paste error logs back here. My guess would be there is some kind of blocking happening, ie DNS lookup possibly try using an alternate resolver ?

I will try and capture a failure with high verbosity enabled, although I doubt its DNS as I have had the same issue using an IP address in the URI as well as using a domain name in it….
