Unexpected error in anvil background function

I am continually getting errors when trying to run an app that was built last year and had run perfectly fine for months. Here is the error code I am getting: anvil.server.ExecutionTerminatedError: Server code exited unexpectedly: 94e54c6d8e

I used to get this when memory ran out. Not a helpful message and took a lot of profiling to find out.

Hello @nvilvovsky,

@masikh is correct. This usually happens because you’ve run out of memory, perhaps your usage has been growing slowly and just hit the limit?
