Background

In very rare cases - especially where queries contain a huge amount of subselects - a query might correctly raise this exception: 'implementation limit reached: too big execution pipeline' (See EXASOL-2345).

Description

After the above-mentioned exception was raised once, other queries (even in different sessions) may also raise this exception.

Expected behavior

This exception is only raised for the corresponding query.
