July 2023 Backtesting Errors "Excessive use of disk face in OnTester Function"

 

Hello

My team and I have been running backtesting/optimization on my expert advisor for the last 6 months. Suddenly on Friday our tests started failing with an error that reads: "excessive use of disc space in OnTester Function, expert rejected my MQL5 cloud network".

Does anyone know what this error is? Was there a change made on Friday July 14th to something on MT5 or MQL5 Cloud Tester?

See screenshot attached.

Thank you

 

The message is pretty clear. Check your OnTester() function.

Post the relevant code if you need coding help.
