Dobrý den .. Chtěl bych se zeptat, kde může být problém, jestli-že mám Gentoo Linux 2006.0 na pc Celeron D 1,7Ghz / 512MB Ram značky IBM (desktop) - sloužíci jako hw server, který musí jet non-stop .. Tedy problém je v tom, že se asi po 3 dnech pc razantně (najednou) z ničeho nic spomalí, včetně času na pc .. Odhaduji spomalení na 60x .. tj za 2 týdny chodu mi takhle ukazoval nekdy i uptime 3dny .. Spomalení se projevuje jen v některých činnostech (každém programu ale jen v určité části) .. Příklad, spustím libovolný herní server, např CS1.6/CSS/ET/Prey apod, u těch se program doslova zastaví po načtení mapy, kdy už by se mnělo dát připojit, server teoreticky je spuštěn, a dá se na něho připojit, protože ten "lag" trva cca 30-50s a 2s jede normálně .. Takto se to pořád opakuje .. Některé jednoduché servery fungují pořád správně .. Ale např DC++ hub posíla clientovi informace o uživatelích asi až po minutě .. Takhle bych asi shodnotil chod programů, jinak připojení přez ssh se mi zdá stejně rychlé, i když možná prace se soubory je pomalejší .. Když celý hw server restartuji - když je "spomalený" - tak se tímto vyřeší problém opět na 2-3dny .. Ovšem než-li ho restartuji, oběví se drobné komplikace s bootovaním .. PC občas vyhodí hlášku že nemohl najít žáden systém k bootu, nebo se spoustení pc (ůvodní screen) drží na obrazovce 20s, a po té mi vypíše info o HW, a pro normální nabootování mám stisknout F2 a poté SHIFT+S, potom už systém naběhne v pořádku .. Jinak celé PC je velmi dobře chlazeno, chlazení je spínací / regulují se otáčky podle teploty = opravdu velmi tiché .. Celé PC na mne působí kvalitní konstrukcí i vybavením .. Myslím, že problém bude někde mezi HW a SW, zkusím pořádně otestovat RAM, i když si myslím, že jsou v pořádku .. Nakonec přidávám log s dmesg:
