also open the same issue(microsoft/vscode-remote-release#2774) in vscode-remote-release

You ran ps -eLf, which shows threads. Each of those threads appear to be associated with the same LS process (17042). The language server doesn't fork (except perhaps to call out to python, which on UNIX-y systems is fork/exec).

Can you run ps without the flag that displays threads (or use a tool like htop) to confirm that it's really only a single LS process?

[MikhailArkhipov]

Does not seem to be LS related. There is no forking in the code. Sounds like VSC remoting issue.

Sorry, so late to reply.
@jakebailey it's only one LS process, but too many threads. And it took about 1 hour to make thread count from 2139 to 4904.

Similar to #2007, then. Making too many threads. Thanks for checking.
