btw nepochopil jsem co dělá reap
Tak ne, tím dockerem to taky není, už to zase spadlo.
A co problém na úrovni distribuce. Nekde nevím kde , možná i na rootu,nebo blogu se během posledního roku mohlo psát o immutable Linuxu.
Má nějaké neduhy. Immutable distr.? Co třeba mount varú,runú do tmpfs, dojde místo někde?
Dobrý den,
nemáte náhodou na server připojena nějaká zařízení pomocí cifs? Třeba pro zálohování někam mimo? V cifs-utils je někde memory leak, postupně sežere celou paměť a server končí přesně jak píšete. Mám/měl jsem stejný problém, dneska jsem nainstalovat update a doufám, že to pomůže. Na serveru mám 64GB RAM, takže vždy chvilku trvalo, než se server zasekl. Sice používám Ubuntu Server 24.04, ale kdo ví, jestli podobný problém není i v Suse.
Petr
Dobry den,
něco podobného jsem řešil s gigabyte brix. Jaky tam mate síťované karty intel e1000?

Pokud si pamatuju, tak inteli sitovky se nemely s tuxem rady, pokud na nich byl zapnuty rx/tx offload. Ale netusim estli se to tyce tvyho modelu.
zjisteni stavu
ethtool -k ethX
vypnuti
ethtool -K ethX rx off tx off
Edit:
Pripadne sem ted jeste nasel v poznamnicku ze problemovy muze byt totok
ethtool -K ethX tso off
Nezdá se mi, že by s tím měl mít cokoliv společného RX, TX offload. Ale nevím, co myslel Peterekcze zmínkou o e1000 nebo e1000e (PCIe) ovladači.
1GbE síťovky od Intelu jedou s těmi zapnutými offloady naprosto běžně ve výchozí konfiguraci a jsou přítomné skoro na všech základních deskách s Intel CPU. V určitých specifických situacích offloady dává smysl vypnout (DPI firewally, zachytávání raw paketů..), nebo pokud to opravdu prokazatelně způsobí problémy (např. bude špatně fungovat škálování TCP okna). Nicméně to rozhodně není tak, že Intel síťovka => vypnu rovnou veškerý offload, to je blbost.
Další věc je, a zas se vrátím k tomu, co už jsem psal. Pokud by tohle nastalo, nejspíš by nevytuhl celý systém tak, že bude třeba vzít natvrdo tlačítkem a nikde nebude ani hláška. I pokud by systém např. po půl dni ztratil jen síťovou konektivitu, tak se krátkým stisknutím spustí normálně shutdown a systém se regulérně vypne, zapíše logy.
Což je i důvod, proč jsem navrhoval, ať se nejdřív zkusí vytížit a otestovat HW, a případně nasimulovat to vymrznutí, aby se tohle vyloučilo a neztrácel čas nějakými softwarovými tweaky naslepo (docker on/off, offload on/off..), zvlášť jestli to předtím fungovalo (předpokládám).
Ale třeba ještě Peterekcze vysvětlí, co měl konkrétně s tím Brixem a e1000.
Myslel jsem přesně toto co již zde bylo poslané: ethtool -K ethX rx off tx off
Toto me vyřešilo můj problém.
Tak i po vypnutí rx, tx a tso problém přetrvává. Byl jsem tam připojen přes ssh a měl výpis journalctl --follow, ale tam nic vidět nebylo. Zaměřím se ještě na tu diagnostiku hw přes live distro.
stress-ng -v --verify --metrics-brief --tz --hdd 4 --hdd-bytes 1G --hdd-opts wr-rnd,direct --temp-path /mnt/datavm/temp/ --matrix 0 --vm 2 --vm-bytes 50% --vm-populate --timeout 5m
První parametr nastaví verifikaci (pokud ji stressor podporuje), --tz ukáže statistiku teploty CPU, pak se tím --hdd zapne paralelní náhodný zápis (4 procesy, každý 1G), pak vytížení CPU s použitím matic (FPU, velký odběr) a automatickým počtem procesů podle počtu jader, pak vytížení pamětí přes --vm a nakonec celková doba trvání testu přes --timeout (jinak se zastavuje ručně přes ctrl+c).@Peterekcze: Ta síťovka opravdu způsobila zaseknutí celého serveru, nebo jen nebyl přístupný po síti? ...Ja mam ve svym poznamnicku napsano, ze s temi offloady po nejaky dobe proste vytuhne kernel. Ale je to poznamka uz pomerne hodne letita, takze to nemusi platit pro aktualni stav.
měl výpis journalctl --followObavam se, ze tohle je ti uplne nanic. I ve zdejsim propadlisti bys nasel ze pokud neco chcipne, tak tenhle pseudologer jde dolu jako prvni, takze zadny logy neuvidis.
