There was another strange problem, after the initial upgrade to.NET 8, there were frequent ssl errors, which did not reappear after I set ssl mode to disable in the connection string

@choby I'm not sure what we can do with such a partial bug report (just a stack trace). I'd need some sort of minimal repro, or at least full statement logging from the PG side to see what is being sent to the database.

I found that if I used tojson() to map jsonb fields, I encountered this problem when I manually enabled multiple UnitOfWorks, and I didn't encounter this problem when I fell back on the tojson() method to HasColumnType("jsonb"). Also note that I made an http request in the UnitOfWork

And this problem seems to exist only in certain scenarios, for example, I run it perfectly in debug mode on my macbook, but I run it 3-4 times out of 10 on ubuntu

from efcore.pg.

@choby thanks for the added detail, but the information above is still very partial, and I'm not sure what we can do to investigate this.

If you can reproduce the problem 3-4 times out of 10 on Ubuntu, please try putting together a minimal, runnable repro (i.e. console application) that does this - a good way is to simply run the code in a loop until it fails. If you manage to do that, please post that back here and we'll revisit. In the meantime I'll go ahead and close the issue as we can't investigate it without a repro.
