We've encountered a strange issue with the trunk version of asterisk.
Our dialplan makes CURL calls and occasionally CURL stops working.
The dialplan looks something like this:
[macro-curl]
; ${ARG1} CURL URL
; ${ARG2} CURL POST
exten => s,1,NoOp(CURL)
...
exten =>
s,n(post),Set(RF_CURL_POST=userID=${RF_DIALER_USERID}&password=${RF_PASSWORD}&${ARG2})
exten => s,n,Set(CURLOPT(httptimeout)=5)
exten => s,n,Set(CURLOPT(conntimeout)=5)
exten => s,n,NoOp(CURL(${RF_URL}/${ARG1}?${RF_CURL_POST}))
exten => s,n,Set(RF_CURL_RESPONSE=${CURL(${RF_URL}/${ARG1},${RF_CURL_POST})})
At this point, CURL either works or it will occasionally hang for a few
minutes. tcpdump doesn't show any traffic from the asterisk box to the web
server.
Something seems to be causing CURL to hang, before it sends out the http
request and the CURLOPT timeouts have no effect on the behavior.
Once CURL hangs, any additional calls to CURL also hang.
After a few minutes, tcpdump will show the CURL traffic going to the web server.
And CURL begins functioning normally for a while.
Has anyone else seen this? Or have any suggestions on how to debug this?
