Hey dagster team, I have been working on migrating an existing dagster project to be deployed via dagster-docker, based primarily on the docs, and have been able to get my jobs working on dagit. The issue I am experiencing using the dagster docker run executor is that my jobs crash without an apparent reason why - the only error message is that the child process exited unexpectedly with error message -11. Any indicator on what this means or likely reasons why the executor would be crashing like this? I saw that for the error message -9 memory issues are usually the cause, is that also the case here?

Hey! According to stackoverflow, this error code usually means a segfault. To trigger taht in python would mean going across the memory boundary, meaning this is likely also a memory issue.

Awesome, thank you - I wasn't sure where to look for more info about what was actually returning the error code! I was able to track down the source of the error, I appreciate the help 🙂
