Re: Server goes to Recovery Mode when run a SQL

But this one is that one which grows and grows memory use until all memory and swap space are gone, so problem occurs. That other SQL which gives us the same problem but immediatelly we couldn´t replay it without our entire database. Even if we extract just that schema to a new DB it doesn´t go to recovery mode. We will think a little bit more to create something you can test.
