What type of issue is this?

Intermittent – Occurring irregularly

Is this issue blocking you from using Enso?

• Yes, I can't use Enso because of this issue.

Is this a regression?

• Yes, previous version of Enso did not have this issue.

What issue are you facing?

I was working on my branch #7779 and noticed that sometimes the engine stops responding.

Here are the logs: https://gist.github.com/vitvakatu/e44a3e410b29c38cfa520f8e80206e52

I couldn't spot any pattern. The issue seems to occur randomly. It happens both on my branch and on develop, and I was only trying engine 9.30.

Expected behaviour

No errors when editing nodes.

Hubert Plociniczak reports a new STANDUP for yesterday (2023-10-12):

Progress: Tried to reproduce problems with applying edits but with no luck so far. Reviewing the design for user libraries in #7955. Fighting with CI which what turns out to be another weird race-condition between background jobs; openfilecmd and closefilecmd don't send replies so there is nothing to synchronize on when defining the tests. General bugfixing. It should be finished by 2023-10-16.

Next Day: Next day I will be working on the #7978 task. Continue the investigation into #7978, make CI pass #7898 to unblock other work.

Hubert Plociniczak reports a new STANDUP for the provided date (2023-10-13):

Progress: Continued with digging through the logs and trying to reproduce the problem (still no luck). Investigated serialization problem reported by James but stacktrace is not very informative (will add more info). While trying to reproduce discovered a major problem with our VCS and modest data directory size - it would always timeout when first opening the project. It should be finished by 2023-10-16.

Next Day: Next day I will be working on the #7978 task. Provide a fix for timeout problems, continue with reproduction attempts for reported stability bugs.

I added some more info so that we have a better idea what is happening from the logs. So far I was neither able to reproduce nor come up on my own with how is that even possible just by looking at the code.
