On a mis-configured or buggy network filer (NFS NAS) writing a large file can cause the filer to freeze.
For diagnostics I need to be able to:
- Suspend (or in other words temporary freeze) all processes of a particular user
- Resume the user
Basically, like a
kill -s SIGSTOP and
kill -s SIGCONT but for the entire user.
To do that, is there a way to temporary take away all CPU-time from a user in Linux?
