sb-concurrency can't pass test on 4GB memory machine with FreeBSD

[David Gao]

I try to build sbcl with sb-concurrency on FreeBSD by using the port system.
When I compile sbcl with sb-concurrency using the machine with 4GB memory, it will report the test fails.
When I compile with sb-concurrency using the machine with more than 4GB memory, the test of sb-concurrency will pass.

When I compile sbcl without sb-concurrency, it will pass either on the machine with only 4GB memory or more.

System info
FreeBSD cn-01 12.0-RELEASE-p10 FreeBSD 12.0-RELEASE-p10 GENERIC amd64

CC info
FreeBSD clang version 6.0.1 (tags/RELEASE_601/final 335540) (based on LLVM 6.0.1)

SBCL version
1.5.5

It can use 1GB at the most, so it's unclear how this is related to 4GB of RAM.

I mean the machines with 4GB memory below, it all fails on test with high CPU load.
I don't know how could you pass the test with a machine with at most 1GB memory. Could you share some details.

[Stas Boukarev (stassats)]

I don't have any details. Maybe freebsd threads are very heavy.

Thanks for the feedback.

Ye, maybe you are right.

I can compile the SBCL with sb-concurrency without the test. And after the sb-concurrency is installed, I can use it without any problems. It is a bit strange.
Maybe I should try it on Linux with 4GB Memory to test if it has any relation with Operation System.
