Hi, friends

My coding style is to typing on a Windows laptop while the real work is done by a Linux machine (Ubuntu server, the standard OS). To build a network connection, I use the ssh function provided by VSCode (the icon at the left-lower corner, so that I can open a remote folder).

I find that when I start to run multithreaded julia programs, even if the cpu resource (of the linux server) is not fully occupied, I will almost surely undergo a disconnection of ssh—that I lose control to my linux machine. Typically the underlying tasks are not killed, i.e., if I attempt to re-connect after 10 minutes, I would see the expected status still there.

But the disconnection is quite annoying. I wonder if anyone can share some experience on dealing with this issue?

(I find it ain’t help e.g. by setting the `nice` level `nice -n 19 julia`, or setting the ssh configure file.)

Do you print too much log in console that the network bandwidth is exhausted?

Take a look in the kernel log (dmesg) and see if you can find a reason for the shell to be killed. In my case it happened occasionally that I had an OOM triggered.
