Redis make test fails on alpine 3.16 image [BUG]

Hi, I'm trying to build redis on alpine 3.16 but when running "make test" it fails with the following output:

[err]: CONFIG SET oom-score-adj works as expected in tests/unit/oom-score-adj.tcl
Expected [get_oom_score_adj] == [expr 1000 + 10] (context: type eval line 8 cmd {assert {[get_oom_score_adj] == [expr $base + 10]}} proc ::test)

make[2]: *** [Makefile:447: test] Error 1

To build redis before testing I ran: make distclean && make V=1 MALLOC=libc && make test

@nadavtsa What version are you using? From the logs, I guess you should be using 7.x. Are you running in docker or on mac M1? Do you fail every time or just this once?

Comment From: oranagra

For the record, we do run our daily tests on alpine (alpine:latest image): https://github.com/redis/redis/actions/runs/3690431795/jobs/6247418673

As far as i can tell, this specific failure looks more like a TCL issue (not a redis issue)

Comment From: nadavtsa

@sundb I'm using redis 7.0.5 and running in docker. I actually solved this issue by setting the oom_score_adj of all processes to zero before building redis with the following loop:

for d in /proc/* ; do [[ -d "$d" && -f "$d"/oom_score_adj ]] && echo "0" > "$d"/oom_score_adj ; done

It seems that for some reason, before building Redis, the oom_score_adj of some processes was already set close enough to 1000 and when the oom test ran the commands:

r config set oom-score-adj-values "10 20 30"
r config set oom-score-adj yes

The OOM Killer was called and killed the process.
