# Tenzir Node v4.17.4

## 🐞 Bug Fixes

### Fix configured pipelines causing a crash when they contain a syntax error

Jun 27, 2024 · [@Dakostu](https://github.com/Dakostu) · [#4334](https://github.com/tenzir/tenzir/pull/4334)

Configured pipelines with retry on error enabled will not trigger an assertion anymore when they fail to launch.

Jun 26, 2024 · [@tobim](https://github.com/tobim) · [#4333](https://github.com/tenzir/tenzir/pull/4333)

We fixed a bug that caused a “Bad file descriptor” error from the python operator, when multiple instances of it were started simultaneously.
