There's just not enough information. Can you reproduce this? Is there anything in the IIS logs showing what file was 404ed? One thing to consider is that there are times where a call doesn't fully connect/disconnect and you will see some random error messages when this happens. I call them "ghost calls" because they are there and not really there at the same time.

Was there a failure case in one or more calls? If not, and you still saw this in the log then it might not be a problem. I see stuff like this all the time in my lab but it doesn't always mean there's a problem.

@Quigath 

its not happening for all call , its very few calls 1% of call were getting disconnect due to bat fetch error . not sure how to fix. its happening in production , could you please help me to fix this issue ?

Is the failure always in the same spot? Often times while the activity log will show a failure in one spot it can mean the failure happened ahead of it. Anything in the error logs? Can you get VXML logs too?

 

david

@david.macias   Is the failure always in the same spot? No not same spot it will be dynamic spot but 1% of the calls were impacted .

 

 

Anything in the error logs? yes

You're going to have to go to your VXML browser logs either from the gateway or VVB. Can you post those?

Thanks!

These are not browser logs. You'll need to get those from the gateway or from the VVB.

 

david

@david.macias 

 

 

please find the VVB logs here , the call ID is 1FF649856BF011EBB6C7D248FA8FCAD9 , please do needful.

 

Thanks in advance!!!!!!

 

 

thanks!

Roy S

I don't believe this is the whole log as the very first instance of that call id shows the timeout error. Need a log with the call from the very beginning.

 

I see you're using Nuance have you look at those logs to see if you're running out of licenses? You can get a bad fetch or no resource when that happens.

 

david

Please find the whole logs here , Thanks Roy

On this log there's a single usable trace of a call (D33626EC6BEF11EBADF4D248FA8FCAD9) experiencing the error you mentioned, however the error seems to have happened after the call was sent to post call survey. It's not clear to me why it happened though as there's not enough verbosity in the logs, but I suspect an API call that is taking longer than 10 seconds, which happens often. I would maybe start with seeing how many more calls are failing in this spot, if a good bit, what happens in the post call survey that might be causing this, then fix. From there go to the next occurrence of the error and track it down.

Thanks in advance 

There are a good bit of bad fetches in those logs, it's going to take way too long through go to them and things are pretty busy right now. You need to identify who is throwing the 404 or what timer is causing this error to be triggered. A few things you want to look at:

- Missing prompts

- Backends that are taking longer than expected and you're not catching the timeout accurately

- Licenses running out

 

Good luck.
