are you able to create podcasts with more than 7 segments or outlines?

[owner-cmd]

because i am having an issue doing that,

AI summary: Issue Summary: Podcast Generation Fails with [Errno 11] EAGAIN on >4 Segments
Environment:

Open Notebook v1.14.0 (Docker)
Railway deployment (8GB RAM, 8 vCPU)
FFmpeg + MoviePy audio processing
Problem: Podcast generation fails when creating podcasts with more than 4 audio segments:

RuntimeError: Podcast audio generation failed: ERROR: Failed to write output audio - [Errno 11] Resource temporarily unavailable

Error occurs in combine_audio_files() during concurrent FFmpeg operations.

Root Cause: File descriptor exhaustion — the worker process has too many files open and can't open any more, which is controlled by a resource limit (RLIMIT_NOFILE). When combining multiple audio clips concurrently via MoviePy/FFmpeg, file handles aren't closed between clips quickly enough, hitting the system limit.

Solution (v1.14.0): Worker concurrency is configurable via OPEN_NOTEBOOK_WORKER_MAX_TASKS and is read at worker launch, so restart the worker after changing it.

Set in .env or deployment config:

OPEN_NOTEBOOK_WORKER_MAX_TASKS=2

Then restart the worker. This reduces concurrent audio processing from default 5 to 2, preventing file descriptor exhaustion.

Trade-off: Podcasts generate slower but complete successfully.
