Hi, I thought that due to high throughput of the linux-kernel mailing list my email will not get a reply if it didn't happen in a day so I allowed myself to write another email to linux-mm as well as it was suggested to me on #debian-kernel. The email is here: Subject: Exhausting memory makes the system unresponsive but doesn't invoke OOM killer Message-ID: <20151223143109.GC3519@orkisz> http://marc.info/?t=145088116000002&r=1&w=2 I have also updated the description in the repository: https://github.com/wodny/crasher Contrary to my original suspicion the OOM killer doesn't need much time to clean up, it just isn't invoked. Johannes Weiner explained the probable cause to me in a response in the linux-mm thread. -- Marcin Szewczyk http://wodny.org mailto:Marcin.Szewczyk@wodny.borg <- remove b / usuĊ„ b xmpp:wodny@ubuntu.pl xmpp:wodny@jabster.pl -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
