[Bug 1783881] Re: ltp-syscalls: msgstress03 fails because systemd limits number of processes

[Dimitri John Ledkov]

What about calling it like this:

$ sudo systemd-run ./testcases/bin/msgstress03

Does that make it pass correctly?

Which resource in particular is exhausted? and can it be toggled somehow
using any of
https://www.freedesktop.org/software/systemd/man/systemd.directives.html
?

Bug description:
  As systemd limits the number of processes, this test will fail because
  it can't fork enough processes. That is limited to when the test is
  run after logging as user 1000, then running sudo. I guess that
  logging as root may not cause this to happen.

  # ./testcases/bin/msgstress03 
  Fork failed (may be OK if under stress)
  Fork failed (may be OK if under stress)
  msgstress03    1  TFAIL  :  msgstress03.c:157:  Fork failed (may be OK if under stress)
