[Spce-user] Malformed JSON string

Mon Aug 27 08:44:04 EDT 2018

Hi Rene and Mika,

Thanks a lot for your response. I will try to upgrade the server to 5.x ASAP for solve this issue. At the moment, I have configured at the end of the file /etc/cron.d/ngcp-fraud-daily-lock this: >/dev/null 2>&1 to try to prevent that the server send e-mails to the root user.

Can this have any impact on the normal operation of fraud prevention? For example, with the sending of emails to exceed the defined fraud limit for a subscriber?

Thanks.

Saludos,
Robert Cuaresma

Hi,

not sure if components were upgrade manually, so make sure

ngcp-api-tools
db-schema
ngcp-panel
templates (in particular the nginx conf)

have aligened version.

If that is fine, you literally see this error because the monster query behind the fraud check takes too long.
This is (was) a known issue, and 5.x introduces better timeout settings therefore.

If you move on to recent 6.x version, you get the billing mappings rasterization refactoring, it speeds up the query by 10+ times.

regards

Hi,

I'm discussing this internally now with Rene Krenn (see Cc).

As a starting point, what ngcp-api-tools versions are you using here? `dpkg --list ngcp-api-tools` lists that.
