Nomadnet shuts down after large message transmit/recieve, possible python issue?

[skatesell]

Hi! I have two identical setups on Lenovo T430 laptops, with Nomadnet 0.4.6, Linux Mint 21.2 Cinnamon OS, with a LilyGO T3 v1.6.1 on 433MHz. The LoRa config is the default from the manual, with the frequency set to the 433 band.

I have had no issues with short message conversations over LoRA.

However I tried sending larger chunks of text, of larger than approximately 1000words, message is sent, but nomadnet shuts down. It restarts without issue, and displays the transmitted message. However it keeps intermittently shutting down when receiving messages, no matter how big payload there is on that message. This continues until the whole system is rebooted. This is the logfile output, it seems to involve python:

Thanks for posting the errors. This is a bug in the UI rendering for large messages, apparently. Probably introduced after the recent updates to Urwid, since rendering very long messages used to work fine.

I cannot replicate this. Have tried with messages up to ~1,300 lines and 55 kilobytes of text, and everything works as intended. Closing for now.
