Subject: [LTP] [PATCH v2] Taunt OOM killer in fork12 setup()
Date: Fri, 7 Feb 2020 09:56:10 -0500 (EST) [thread overview]
Message-ID: <1149510045.6536246.1581087370399.JavaMail.zimbra@redhat.com> (raw)
In-Reply-To: <20200207145403.23193-1-mdoucha@suse.cz>
----- Original Message -----
> On a system with low memory, fork12 can trigger OOM killer before it hits
> any fork() limits. The OOM killer might accidentally kill e.g. the parent
> shell and external testing tools will assume the test failed.
>
> Set high oom_score_adj on the children of the main fork12 process so that
> the OOM killer focuses on them.
