Unattended robot pausing execution intermittently

[jonathan.teo]

Hi,

I have an unattended production robot that is running a number of flows through the day.
However, there occasionally there are times when the job execution freezes randomly at different steps.
There does not seem to be a commonality whenever it happens as it happens at different steps randomly.
In the screenshot below it is frozen only on a log message action.

Once the job processing is frozen there are no errors logged and the job is paused there indefinitely, holding up all other queued processes until it is manually killed.

Any advice is appreciated.

Best Regards,
Jonathan

Adding on to this, the error does is not limited to this process flow and happens randomly across other processes.
