Can't build openjdk:jdk 16 and above on aarch64 without hitting TasksMax

Can't build openjdk:jdk 16 and above on aarch64 without hitting TasksMax

[Brennan Vincent]

for historical context.

I have to bump this value locally in order to build openjdk@16:jdk
because the build requires more than 10000 PIDs.

Perusing the output of ps suggests that the build process is leaking a
huge number of unreaped bash processes. The number keeps growing
monotonically until the build is finished.

Sounds like a functional programmer at work!

Kind regards

This may well be related to an old bug, fixed in ‘core-updates’:

  https://issues.guix.gnu.org/30948

Plan is to merge it in the coming days!

I should have mentioned that I'm on a foreign distro (Fedora). Which if
I correctly understand how things work means I'm not using the Shepherd
at all. Is the patch you linked relevant anyway?

Yes: the bug in question meant that zombie processes could pile up in
the build environment.  This is now fixed, with PID 1 in the build
container taking care of reaping processes.
