File transfer failure with large files using Warpinator between Linux Mint systems

Distribution

Mint 22 -- Mint 22

Package version

1.8.6 (Distro version)

Frequency

Always

Bug description

While attempting to transfer approximately 70 GB of files (two files of 30 GB and 40 GB) between two Linux Mint 22 hosts using Warpinator, the transfer failed with a "Finished, with error" message.

After the transfer failure, the two hosts are unable to detect each other. Restarting Warpinator on both hosts allows them to reconnect, but the transfer fails again when retried. Out of about 10 attempts, only 1–2 succeed. This issue seems to persist consistently with large file transfers.

Steps to reproduce

1. [Sender/Receiver] Launch Warpinator on both systems.
2. [Sender] Add large files (approximately 70 GB in total, consisting of two files: 30 GB and 40 GB) to the transfer queue using drag-and-drop.
3. [Receiver] Accept the transfer request by clicking the "Accept" button in Warpinator.
4. The file transfer fails with a "Finished, with error" message.
5. Both computers are no longer able to detect each other (appear as Offline).
6. Restarting Warpinator on both systems allows the computers to detect each other again (appear as Online).

Expected behavior

Transfer success!

Additional information

Sender log: sender_log.txt

Receiver log: receiver_log.txt

Start by reviewing sender_log.txt and receiver_log.txt, then reproduce the transfer between two Linux Mint 22 systems with files around 30–40 GB. Trace where the transfer reports an error and where both hosts become Offline; done means repeated large transfers succeed and the hosts remain discoverable without restarting Warpinator.
