drokz:~#

Zo, dat stond er vanmorgen in mijn dmesg

volgens google results betekend dit dat er niet geswapped is terwijl daar alle mogelijkheid voor is:

code:

drokz:~# free -m
             total       used       free     shared    buffers     cached 
Mem:            70         64          5          0          2         25
-/+ buffers/cache:         36         33
Swap:         1349         11       1337

Dus mijn vraag is, hoe zit dit nou. Zou ik toch maar moeten rebooten of...

de load is bijv. ook totaal niets:

code:

drokz:~# cat /proc/loadavg
0.03 0.05 0.03 1/125 8548

Het gaat om een Xen Dom0 host machine met daarin 5 virtuele machines. Het totale ram is 1GB.

Debian Linux, kernel 2.6.16-2-xen-686 op een Pentium D 2.8ghz

uptime is inmiddels de 75dagen al voorbij.

[MTWZZ]

Ik heb zelf ook een keer zo'n melding gehad maar de server waarop dat gebeurde draaide gewoon zonder problemen verder. Later bleek dat er 1 van mijn progsels ineens gigantisch veel memory opslurpte in een absurd korte tijd (beetje memory forkbomb )
Dus ik zou het in de gaten houden en niet rebooten als het er niet op lijkt dat er meer om zeep wordt geholpen.

[moto-moi]

Out Of Memory killer staat het voor, dus blijkbaar was zowel je interne geheugen als je swap vol en had de machine toch meer geheugen nodig. En dan gaat hij dus processen killen, tegenwoordig met wat meer intelligentie dan vroeger (vroeger knalde hij @ random eentje af als ik me goed herinner )

Dus het beste wat je kunt doen is meer geheugen in die bak prikken want 70MB is nou niet bepaald veel

[odysseus]

Ter verduidelijking: hoewel meestal wel het geval, is het niet gegarandeerd dat de OOM-killer pas in actie komt als ook al je swapspace gevuld is. Je RAM zit met maar 70MB snel genoeg vol, dus de kans is daardoor aanwezig dat je OOM-problemen krijgt. Zie voor iemand met een vergelijkbaar probleem hier. Overigens is het de vraag of een zo grote swappartitie bij zo weinig RAM wel zinnig is - alleen bij heel veel programma's die allemaal om de beurt een keer iets gaan doen heeft het nut. Met weinig programma's heeft het logischerwijs weinig nut en als meerdere programma's iets gaan doen, dan moeten die ook in het RAM komen, anders wordt de snelheid wel erg dramatisch .

[nzyme]

er draaien slechts de Xen processen + sshd. Verder natuurlijk kernel procs en syslogd etc.

Vreemde zaak dus iig. En het doel van swap is toch om toch meer geheugenruimte te bieden als je fysieke hoeveelheid op is ?
iig zal ik even dynamisch upgraden naar 128mb een reboot is dan niet nodig. xm mem-set Domain-0 128 is voldoende om "ineens" 128MB ram te hebben..

[_JGC_]

Ik kwam vandaag bij het configureren van MySQL ook nog een hele leuke optie tegen: een mogelijkheid om geheugen te locken, waarbij de kernel het geheugen niet gaat uitswappen. Als je maar genoeg zooi hebt die dit soort praktijken uitvoert ben je snel genoeg door je geheugen heen en gaat OOM aan de slag, ondanks dat je swap nog niet vol is.
Daarnaast: vanuit swap kan niets uitgevoerd worden, het is alleen een tijdelijke opslagplaats waarin ongebruikt geheugen wordt weggezet. Op het moment dat jij meer dan je beschikbare RAM tegelijk moet aanspreken kan je nog zoveel swap hebben, maar gaat het gewoon mis.
