Oom-killer zonder geheugengebrek
Hallo,
Ik heb een raar probleem: oom-killer wordt aangeroepen terwijl er geen
tekort is aan geheugen. Swap wordt niet aangesproken.
Heeft iemand een idee wat dit zou kunnen zijn?
Het zou een probleem met het swap-geheugen kunnen zijn, daarom heb ik
dat net opnieuw aangemaakt met "mkswap -c", van "check".
Ik zie ook verschillende keren de term "tainted" voorbij komen, terwijl
ik geen closed-source drivers gebruik op deze machine. Zoiets:
Mar 13 07:37:22 host kernel: [938438.416551] CPU: 1 PID: 12538 Comm:
find Tainted: G W 4.9.0-0.bpo.1-686-pae #1 Debian
4.9.2-2~bpo8+1
Er wordt ECC geheugen gebruikt.
Groeten
Paul
