Hi Neil, 

Just a guess, shouldn't you put a significant sleep before "c.disconnect()". Since the previous command starts background api, it would be appropriate to introduce some time gap before disconnecting ESL.

Hi Brian,

Sorry, I didn't give enough context.

The code below is for the origination of calls, which we are doing through ESL and where the connection is being unexpectedly dropped, or even if not dropped, no record of the origination appears in either FS logs or CDR. 

CDRs are being generated to sqlite and we are reading them from there asynchronously.

Also forgot to link the documentation that suggests building from source is the way, it's here

You're doing the CDR collection inline or what are you speaking of exactly?

Hi all, I have a fresh server running FS 1.8 from package on Debian 9. It runs a python app connecting to FS using ESL that executes this code per call attempt:

c = ESLconnection(str(settings.ESL_HOSTNAME), str(settings.ESL_PORT), str(settings.ESL_PASSWORD))

if not c.connected():

    abort()

dial_command = "originate …"

ev = c.api("bgapi", str(dial_command))

c.disconnect()

if ev:

    result = ev.serialize()

    logger.debug('API result = {}'.format(result))

When we ran 350K call test, 70K calls got to this code and failed the final if condition, meaning ev was None. No CDR generated.

This is totally an unexpected error case for us after tens of millions of calls over last 3 years on our other servers. Any idea why this is happening? The only difference I can see is we’ve not seen this issue on FS 1.6 (built from source), so maybe it’s introduced in 1.8 (run from package)? FYI we've built pyESL from source, which is what's recommended here. Any chance there is an incompatibility between pyESL built from source and FS 1.8 installed from package?

Thanks,

Neil
