I've got a couple of antlets (Ubuntu 18.04) that I'm running Samba on to move files between various places on my network. So far today I've had to reboot the entire Antsle box 6 times because, during the file transfer, one of the antlets completely locks up and craters the entire system. It can't be rebooted. It can't be connected to via console/VNC/etc. It can't be shutdown in the antsle interface. The only way to fix it is to reboot the system (and any other antlets running that AREN'T grossly malfunctioning).
Is there anything I can do to fix this? In general, samba file transfers have been pretty disappointing, so if there's another option, then I'll try it.
EDIT: installed a FTP server and tried to transfer a few large files. Same problem. Maybe something jacked with the ethernet driver?
