Message Stuck in Processing then moved to Abandoned

Hi,

I have an interface which will be processing a big data coming from XI (Sproxy) from SAP. The size could be vary from 500mb to 1Gb

The problem is that, when the file is almost 1Gb (960mb), the message will be stuck in Processing status then move to Abandon status after some time. This is the Error Detail message when the status changed to Abandon:

Message processing was abandoned because of inactivity timeout of 24 hours

I suspect this is due to memory issue in the CPI tenant? How to check how much resource my tenant has in CPI?

Thank you
