Error message and I dont know the exact cause as its happened a few times on multiple workflows and symbols

I had left it to run overnight and returned to find this error. Tried to run it again from OOS5 and it wouldn't run at all just spitting out this error. Full log attached as a file and the config for the specific OOS 5. Hope you can work it out.
