Cannot connect using VS Code

[Anonymous Student]

I get an error about “resource unavailable” or something about “fork” and VS Code will not connect to Eddie.

There are tight limits on how many resources a single user can use on each login node, and this error message suggests you have reached the limit. Running VS Code and tensorboard on the same node may exceed the limit.

This is usually because you already have processes running on that node. You need to find them and terminate them. In a terminal on your local computer, ssh to the login node in question, then try some of the following:

# kill all VS Code processes
killall -KILL node

You might need to repeat the above until you eventually see node: no process found. Ignore any “Operation not permitted” messages – those relate to processes of other users (don’t worry – you cannot kill those!)

# kill all Tensorboard processes
killall -KILL tensorboard

If that doesn’t help, find all other processes belonging to you:

ps -elf | grep s1234567

and kill any that you no longer need (of course, if you kill your login shell, you’ll simply be logged out without warning).

kill -KILL <insert process number here>
