The service stops spontaneously

Problem

This situation may occur in case:

the client has exceeded the limit specified in the addon settings;
not enough funds to make the payment.

Solution

The client has exceeded the limit specified in the addon settings

Check in the tariff plan settings or service settings what value is specified in the limit.
Check the service history for when and by whom it was disabled. For example, if in the service history it was stopped by pmispmgr5 service.postsuspend, you can view the /usr/local/mgr5/var/pmispmgr5.log at the time of stopping and check the cause.
The moment of service stopping due to exceeding the limit of the addon in the /usr/local/mgr5/var/billmaintain.log will appear as follows:

```
Note:
If the limit is exceeded, the client must receive a notification.

Not enough funds for payment

Check the balance, time of last topup, notifications.

Check billmaintain.log for any errors.
