Cloud Pak for Integration

Hi All,

I am stuck with an issue which am unable to understand the cause of it's happening so I have a Linux server where my ACE is installed and I have created broker and an execution group in which we have deployed around 25-30 REST API one of my api is an SMS API where we are using http request node to send a request to a vendor to send sms on the given mobile number am facing an issue where my sms api suddenly goes down note all the other api and broker are up and running just the sms api goes down and I get an "Internal Error" but when I reload the broker the issue is gone and the api is up and running, I am unable to pinpoint the issue or a solution for the same kindly please let me know if anything can be done.

Regards,                                                                                                                                                                                                                                     Raza
