Re: [SR-Users] What could cause an intermittent fault (28) with http_query()?

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….

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 ?

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, _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users@lists.sip-router.org<mailto:sr-users@lists.sip-router.org> http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
