@bogdan-iancu The fix seems to work fine for us. The error is gone now. --- You are receiving this because you are subscribed to this thread.

Thanks for the fix, I will try out and update you. --- You are receiving this because you are subscribed to this thread.

Try this: https://www.dropbox.com/sh/93j7gdfwk2h5lnq/AACGTMrj6zKaXHjw_YBQBm84a?dl=0 I wasn't able to reproduce the successful case this time. It's failing all the time. --- You are receiving this because you are subscribed to this thread.

Re: [OpenSIPS-Devel] [opensips] Problem with using async and exec (#829)
Here is the log file with additional logging requested: https://www.dropbox.com/sh/93j7gdfwk2h5lnq/AACGTMrj6zKaXHjw_YBQBm84a?dl=0 I was able to reproduce both successful (good_async.txt) and failure (bad_async.txt) cases. Please search for in the logs to identify the async+exec+curl web request: ` Submitting web service get request - http://255.255.255.29:80/ws/index.php/query_client_ready_for_call` Also, I found that in the failure case, the following log statement is missing: ``` Mar 22 19:48:27 osips[14660]: NOTICE:core:io_wait_loop_epoll: EPOLLIN(read) event: epollwait() set event EPOLLHUP - connection closed by the remote peer! Mar 22 19:48:27 osips[14660]: NOTICE:tm:io_watch_del: [UDP_worker] io_watch_del op on index -1 37 (0x848de0, 37, -1, 0x10,0x1) fd_no=3 called ``` Thanks for the bug triage! --- You are receiving this because you are subscribed to this thread.

Re: [OpenSIPS-Devel] [opensips] Problem with using async and exec (#829)
Yes, I can still reproduce it. **Note: **First query is done independently. The second query i.e., port 49864 (/ws/index.php/...) is causing this problem. If you can provide me a patch with extra logging to the module, I can experiment and get back to you. --- You are receiving this because you are subscribed to this thread.

Re: [OpenSIPS-Devel] [opensips] Problem with using async and exec (#829)
**More information:**
I tried the following:
`
async(exec("sleep 4", "", "$var(restGetResponse)"), RT_RESUME_AFTER_RESPONSE);`
I still the error. Makes me wonder whether async+exec is the problem here.

Re: [OpenSIPS-Devel] [opensips] Problem with using async and exec (#829)
Hi @bogdan-iancu,
Yes, there was a connection attempt in both the failure and success cases. So
more information:
a) Curl makes a webrequest. Webservice will block until a timeout say 4s. Hence
we used async for scalability.
**Success Case:**
```
osips[6987]: RequestRoute[RT_HANDLE_PSTN_REDIRECT]: Submitting web service get
osips[6987]: NOTICE:core:io_wait_loop_epoll: EPOLLIN(read) event: epollwait()
set event EPOLLHUP - connection closed by the remote peer!
osips[6987]: ResumeRoute[RT_RESUME_AFTER_RESPONSE]: Async web service request
returned
```
**Failure Case:**
```
osips[6611]: RequestRoute[RT_HANDLE_PSTN_REDIRECT]: Submitting web service get
request
osips[6611]: NOTICE:core:io_wait_loop_epoll: connection closed by the remote
peer!
osips[6611]: ERROR:core:io_wait_loop_epoll: [UDP_worker] unexpected event 10 on
1/1, data=0x7f8bce9f3b50
osips[6611]: NOTICE:core:io_wait_loop_epoll: connection closed by the remote
peer!
osips[6611]: ERROR:core:io_wait_loop_epoll: [UDP_worker] unexpected event 10 on
1/1, data=0x7f8bce9f3b50
```
In both the cases, I verified using wireshark that the tcp connection was made
with the server and server replied back with a response:
`{"result":"timeout"}`

2nd one is the faulty one i.e., port 49864 (/ws/index.php/...). I will be deleting the content of the dropbox since you downloaded it. --- You are receiving this because you are subscribed to this thread.

Re: [OpenSIPS-Devel] [opensips] Problem with using async and exec (#829)
Here is the dropbox link to the pcap: https://www.dropbox.com/s/jod9zdifa93d5yv/trace_2016-03-16_20_55-UTC.pcap?dl=0 It has webrequests made to port 80.

[OpenSIPS-Devel] [opensips] Problem with using async and exec (#829)
We are using async and exec to make a web-request as shown below:
$var(fullQueryClientReadyRequest) = "an url with params";
async(exec("curl --connect-timeout 30 --max-time 30
\"$var(fullQueryClientReadyRequest)\"", "", "$var(restGetResponse)"),
RT_RESUME_AFTER_RESPONSE);
We see the following (printed several times):
> osips[16437]: NOTICE:core:io_wait_loop_epoll: connection closed by the remote
> peer!
> osips[16437]: ERROR:core:io_wait_loop_epoll: [UDP_worker] unexpected event 10
> on 1/1, data=0x7f215063bb68
After this happens, the process becomes unresponsive.
**Note:** We do not use $var(restGetResponse) in the RT_RESUME_AFTER_RESPONSE.
However, we have it so that the exec will be blocking.
