NoSuchElementException for for pastes logger than ~50 rows

[katoquro]

After week of usages pastefy has started to throw 500 error codes on some responses

{"success":false,"exception":"NoSuchElementException","error":true,"exists":false}

However very small pastes (like 30 rows) still work.
Sometimes long pastes with code works well.
When I'm trying to save stack trace (about 200 row) it fails very often

I use docker image 6.6.7 with maria-db from compose

Stack trace from server log
